That's all from this minute-by-minute commentary - thanks for joining me. Match report, reaction and player ratings to follow.
England face Costa Rica in Belo Horizonte on Tuesday, but it will be a strange occasion. Second-string line-ups on show, more than likely.
Full-time: Italy 0 Costa Rica 1 (Bryan Ruiz 44). England are out of the World Cup; Costa Rica are through to the last 16.
Cassano connects with Cerci's corner but he can only pok a shot wide off the goal under pressure from Umana.
Costa Rica will qualify if they win this game, but they won't win the group tonight. Under FIFA rules, if teams are level on points they will be separated by goal difference, then goals scored and then on the head-to-head record between the sides.
Great recovery from Chiellini as Urena escaped into the box. The Juventus centre-back stood up and blocked the shot.
Costa Rica allowing Italy to have more of the ball now. The Azzurri are up to 59% possession in the match, but they don't look like scoring at the moment.
Urena tries to make space in the box but he can't keep hold of the ball and Italy launch another attack. The Azzurri look disjointed, however, and that spells bad news for England. Costa Rica are on course to win Group D here, leaving Italy and Uruguay in a straight shootout for second place.
Second change for Costa Rica - Urena ON, Campbell OFF. Marcos Urena scored after coming off the bench against Uruguay on Saturday - can he do the same again here?
YELLOW CARD! Balotelli is the first player booked this afternoon (69). The Italy striker petulantly pulled back Duarte in the box, a good spot by the linesman.
The Costa Rica fans are having a marvellous afternoon in Recife. The Italy supporters look pig sick.
The flag keeps going up against Balotelli. The Italy striker has now committed six offside offences in this World Cup campaign. Robin van Persie is next on the list with five.
Another scare for Italy as Buffon has to come far out of his goal and clear the ball. Danger averted, however,
Great work by Bolanos and Junior Diaz on the left flank to keep the ball alive. The latter, who plays for Mainz, has got forward so well from his left-back berth. Could be a transfer target for Premier League clubs - he has bags of energy.
An excellent Pirlo free-kick from 30 yards out gets a slight deflection off the Costa Rica wall and carries on towards goal, where Navas is able to beat the ball away.
Navas makes a fingertip save to divert Darmian's powerful shot over the crossbar. The Torino defender had cut in from the left flank before letting fly.
Cassano receives the ball on the right side of the box but Costa Rica are alert to the danger very quickly.
Duarte tackles Balotelli inside the box. It's an excellent challenge, and the ref isn't fooled by the Italy striker exaggerating the contact.
England supporters are trying to stay positive with their team just 45 minutes away from elimination as it stands. Chris Green emails in to say: "Looks like the lads are set for an early flight home, but I still believe the Italians are capable of getting the result we desperately need."
On email, James Cleland asks of goalscorer Bryan Ruiz: "Why can't he play like this in his other white shirt... for Fulham?!!" It's a question that a lot of Cottagers fans will be asking. Ruiz scored five goals in 14 Eredivisie games for PSV Eindhoven in the second half of last season - maybe the west London club should have stuck with them, they might have stayed up.
Italy are now available at 11/4 with Sky Bet, while the draw is 15/8. If you think Costa Rica will go on to win, it's evens. Among the HT price-boosts, Joel Campbell is 12/1 for the next goal - that looks tempting.
The Costa Rica coach Pinto's reaction to the penalty appeal is understandably lively. Stats show Costa Rica have had seven shots with four on target, Italy with five shots and only one on target. England going out of the tournament as it stands.
You have to say that's justice for Los Ticos, as Campbell was clearly pushed over by Chiellini in the box just moments before - only for the referee to somehow miss it. A magnificent Diaz cross and Ruiz header has Costa Rica ahead, however.
GOAL FOR COSTA RICA! A wonderful inswinging left-wing cross from Junior Diaz arrows towards Bryan Ruiz at the far post and his header hits the bar and bounces down over the line - as confirmed by goal-line technology. 0-1.
A big decision from the Chilean referee! Campbell goes down in the box between Chiellini and Barzagli and it looks like a penalty - but Mr Osses tells him to get up and play continues.
Ruiz crosses in from the right and Duarte leaps to head the ball, but can only send it over the crossbar.
Ruiz with a low shot from 25 yards out after skipping round De Rossi. Didn't catch it properly and Buffon can claim it comfortably.
Italy have the upper hand on possession now - 54% to 46%. Both teams have had four shots each, with Italy getting one on target and Costa Rica two.
Buffon gets down low to his left to deny Bolanos. Ball was curling towards the bottom corner, but the Italy captain pushes it around the post.
Navas saves a fierce shot from Balotelli, on the volley from the edge of the area! Set up by Motta. And then the Costa Rica goalkeeper clutches the ball at the second attempt as Marchisio was lurking. Replays show Balotelli was offside as the pass was knocked in to him.
Best chance of the game so far! Pirlo releases Balotelli with a glorious pass down the right channel over the top. The striker's first touch is a bit heavy and he then lifts the ball over the onrushing Navas, but he gets it wrong and the ball bounces wide of the target.
A low shot from Thiago Motta goes wide of Navas' right-hand post. Balotelli nodded the ball into Motta's path from Pirlo's floated cross.
The linesman flags for offside against Balotelli as the cross comes in from the left, but it's a bad decision - he was level.
Gonzalez does well to take the ball away from Balotelli in the area, and is then pulled down by the AC Milan striker. Another free-kick to Costa Rica.
Midway through the first half now. Costa Rica lead possession 55% to 45%, and have had three corners to Italy's one.
Campbell's corner is far too deep, but Duarte retrieves the ball and crosses powerfully into Chiellini's forehead. Ouch! The Juventus defender is as tough as they come, though.
Campbell does well under pressure from Darmian to retain possession and although his ball into the box is cleared, Los Ticos keep pushing and eventually win a third corner. TV replays show it should have been a goal kick, however.
Buffon punches the set-piece away. Costa Rica soon launch another attack but this time the Italy veteran can gather the ball.
England supporter Carlos Holley remains optimistic on email: "I think the final score will be 3-1 to Italy... I hope anyway."
Italy win their first corner off Gonzalez, but the Chilean referee Osses awards Costa Rica a free-kick for a push by Balotelli in the area.
Some breaking news for you England fans following this commentary: FA chairman Greg Dyke has told Sky Sports News that England manager Roy Hodgson will remain in his post until 2016.
First corner of the game to Costa Rica after Barzagli blocks from Tejeda... and it's headed over by Borges from close range! Buffon was nowhere near saving that, but it came off the top of Borges' head and went over.
Duarte is lucky not to be booked for pulling back Marchisio. Very fortunate for the Costa Rica defender.
A tweet from England striker Daniel Sturridge: "Come on Italy!! Necessita il primo dei due favori! Learnt that from the local Italian chef. .. #badtimes #inGodshands #ForzaAzzurri " Think that translates as 'do us a favour'...
Diaz wins a throw off Candreva on the left flank. Costa Rica keeping possession well in the opening exchanges.
Bolanos with a tame low shot from long range - an easy save for Buffon. Good build-up initially from Costa Rica, however.
The Costa Rican anthem remembers the forefathers of the nation who earned "eternal renown, esteem and honour". The current crop of Ticos heroes will surely be up for the same acclaim if they can get a result here today,
The Italian national anthem is of course a corker. "Siam pronti alla morte" - we are ready to die! - is one of the lyrics, and England fans will be hoping the Azzurri show that sort of will to win today.
The teams are emerging from the tunnel at the Arena Pernambuco. Italy will be in all blue, Costa Rica in all white.
A couple more Sky Bet Price Boosts for you. If you fancy Costa Rica to cause an even bigger upset in Recife, consider Cristian Bolanos to score first at 16/1 and a 2-1 Los Ticos victory at 22/1.
15 mins from kick-off, and Liverpool supporter Cian Hughes has emailed in to say: "Enjoyed watching Suarez playing yesterday. I think Costa Rica will not do too bad today and I'm not sure if they can beat an Italian side. 2-2 draw!"
What might concern England fans is Italy's recent run of results. Saturday's victory over the Three Lions in Manuas was the Azzurri's only win in their last eight full internationals. Since beating the Czech Republic 2-1 in World Cup qualifying in September, they drew with Denmark, Armenia, Germany and Nigeria; lost 1-0 to Spain; and then drew with the Republic of Ireland and Luxembourg. They did, however, win 5-3 in an unofficial friendly against Brazilian club side Fluminense shortly before the World Cup began.
Winning the match is a tall order for Pinto's side, but the odds of scoring at least one goal look to be in Costa Rica's favour. Los Ticos have scored in each of their six World Cup games against teams from the UEFA confederation.
So can Los Ticos pull off another shock? Not according to our pundit Paul Merson, who predicts a 2-0 Italy win. He said: "If I'm being honest, I didn't think Costa Rica were all that (v Uruguay) and I thought Italy were decent. But, of course, we didn't pick up Andrea Pirlo - he just did what he wanted to do - and I think Roy Hodgson got that wrong as well. Costa Rica weren't that good; Uruguay were just shocking at the highest level. I mean, the boy Joel Campbell looked like a world beater but I've got more chance of playing for Arsenal next season than him. Seriously, there's no way he's playing for Arsenal next season. Fair play to him but he's got no chance. We've got to cheer on Italy to win."
With Gianluigi Buffon returning to the Azzurri starting line-up, he becomes the fifth Italian to play at four World Cup tournaments. Gianni Rivera, Giuseppe Bergomi, Paolo Maldini and Fabio Cannavaro are the other four.
Andrea Pirlo will be the main man for Italy in midfield - he made 108 passes for Italy v England, but interestingly 59 of them were in his own half. If you fancy him to nab the first goal of the game against Costa Rica, you can get Price-Boosted odds of 10/1 with Sky Bet.
Here's Eric Moynihan on email: "I'm not sure why people are writing off England chances yet. I fully expect Italy to beat Costa Rica, and it's a toss of coin between Italy and Uruguay. England will beat Costa Rica - and I think will beat them well. Uruguay are not world beaters and I certainly wouldn't be backing them to beat Italy. They might get a draw, but again it's the toss of a coin. And I'm an Irish fan, but would love to see them go a bit further than than the groups."
Azzurri coach Cesare Prandelli has voiced his concerns about the temperatures in Recife, having struggled at the same venue last summer when beating Japan 4-3 at the Confederations Cup. That was a 9pm kick-off local time - today it's 1pm. Currently, it's 28 degrees celsius with 70% humidity - so probably not as bad as feared for Italy.
Anything other than an Italy win spells disaster for England. If history is a factor for you, you'll be worried by the stat that Italy have failed to win their second game at a World Cup finals in each of the last three editions of the tournament.
Let's take a closer look at the betting for tonight's game. Italy are 8/15 with SkyBet, while the draw is 16/5 and Costa Rica can be backed at 11/2.
Chris has also asked which player has impressed the most at the World Cup so far. For me, I think the main contenders are Robben, Muller and Messi. I'll go for Robben so far. I also think James Rodriguez has been excellent for Colombia. But it's early days and there are lots of contenders!
Our first prediction of the afternoon comes from Chris Green in Huddersfield via email: "Italy to win 3-0, with Pirlo and Balotelli (2) scoring the goals." You can get odds of 11/1 on that with SkyBet - it's been Price Boosted.
Italy and Costa Rica have only met once before - in a warm-up match before USA 94. The friendly in New Haven, Connecticut, was settled by a solitary Beppe Signori goal.
Jorge Luis Pinto chooses an unchanged Costa Rica team following the 3-1 victory over Uruguay in Fortaleza on Saturday.
Costa-Rica line-up (5-4-1): Navas; Gamboa, Duarte, Gonzalez, Umana, J Diaz; Ruiz, Borges, Yeltsin, Bolanos; Campbell.
So Cesare Prandelli makes three changes to the Italy side that began the 2-1 win over England in Manaus on Saturday. Captain Gianluigi Buffon returns from injury to replace Salvatore Sirigu in goal. Thiago Motta came on for Marco Verratti in the Group D opener and now replaces him from the first whistle, and right-back Ignazio Abate is picked ahead of Gabriel Paletta. As a result, Giorgio Chiellini moves from left-back to centre-back, and Matteo Darmian moves from right-back to left-back.
Italy line-up (4-1-4-1): Buffon; Abate, Barzagli, Chiellini, Darmian; De Rossi; Candreva, Motta, Pirlo, Marchisio; Balotelli.

Of course, this encounter has taken off enormous implications for England, who need Italy to win to have any chance of progressing to the last 16 of the tournament.
