All over, and Olympiakos end their Champions League campaign with a victory. Defeat for much-changed Arsenal, but they still take their place in the draw for the last-16 and can be content with their work in this competition despite a poor second-half showing here.
A late yellow card for Chamakh as he tries to get through on goal by punching the ball forward. Not subtle.
Wonderful crossfield pass from Oxlade-Chamberlain to set Gervinho away down the left, but he uses an arm to bring the ball under control.
Meade makes way for Martin Angha. The left-back's display has been a bright spot for Arsenal tonight.
Smart, driving run from Oxlade-Chamberlain takes him into the penalty box, but his cross is too high for Chamakh.
Quick feet from Arshavin on the edge of the box creates a shooting opportunity, but Manolas gets a good block in and sends the ball spinning behind for a corner.
Olympiakos sweep forward. Real swagger about their football now with both full-backs getting forward at will. Fuster's overhit pass ends the break, but the hosts are looking to add to their tally here rather than merely protect the lead.
Gervinho goes down in the penalty box as Contreras leans on him, but the penalty appeals are half-hearted at best. Goal-kick.
All Olympiakos now, but Djebbour wastes a promising position with a pass to no-one on the edge of the area.
GOAL - MITROGLOU! He's only been on the field for a minute, but he's given his side the lead in fine style with a fizzing, curling shot that zips past Szczesny and inside the far post. It's a brilliant finish.
Olympiakos should be ahead. Wonderful low cross from the right finds Djebbour in space after ghosting past Jenkinson, but he somehow heads wide from six yards.
Squillaci a touch fortunate to see only a yellow card after chopping down Djebbour, who had a chance to run on goal.
Szczesny booked for dissent after that goal. Think he was arguing against the initial award of a corner, saying the ball went behind off the post rather than his hand.
GOAL - MANIATIS! Olympiakos level. The corner is half-cleared and, when it's helped back into the box, Ramsey inadvertently chests the ball into the path of Maniatis who scores from close range. Arsenal back down to second.
Arsenal's defence goes AWOL to give Machado a free header eight yards from goal, but he makes poor contact and Szczesny is able to scramble the ball behind for a corner.
More tidy defending from Meade as Olympiakos probe down the right. The little man has done little wrong.
Chamakh and Gervinho link up before working the ball to Arshavin whose driven effort is well saved by Carroll.
Wonderful pass from Abdoun to play in Fejsa, but he gets his feet in a tangle and tries to finish with the outside of his right foot rather than his left foot. Finds only the side-netting.
Torosidis can't quite get the ball under control out on the left, and Jenkinson is able to smuggle the ball behind for a goal-kick.
Gervinho's careless pass allows Olympiakos to launch a quick counter. Abdoun bursts past Oxlade-Chamberlain but then makes a mess of a one-two with Greco.
Wonderful break from Arsenal, Oxlade-Chamberlain's deft touch sending Chamakh away down the right. His cross is early and picks out Arshavin, but the Russian - not famed for his aerial prowess - heads over the bar. Might've preferred that ball whipped in along the deck.
Coquelin plays Squillaci into trouble, and he fouls Greco trying to recover the situation. Nothing comes of the free-kick.
Ramsey takes the free-kick, hammers it straight into the wall and falls over. Rather sums up his night.
Fejsa earns the first booking of the match after cynically pulling Gervinho's shirt as the Arsenal man looks to burst clear.
Ramsey swings the ball into the box and Chamakh gets a glancing header to the ball but there's not enough pace on the ball to trouble Carroll.
Arsenal win a free-kick in the centre-circle. They play it short and start another patient spell of passing.
Olympiakos get the second half under way. Arshavin replaces the impressive Rosicky, perhaps with an eye on the weekend.
Betting update from Sky Bet. Aaron Ramsey to score next is 18/1, while the Gunners to end up 2-0 winners is 7/1. Can the hosts turn it around? We go 7/1 for Olympiacos to steal a 2-1 win.
Half-time whistle goes. That'll do for Arsenal, who produced the one moment of real class in a generally lacklustre game as Gervinho's run and perfect cutback allowed Rosicky to run onto the ball and calmly sweep it inside the far post. It's still Montpellier 0 Schalke 0 and if both scorelines remain the same Arsenal will finish top of Group B.
Ramsey perhaps lucky not to be penalised as he tangles with Greco and the Olympiakos man goes to ground. The ref's looking to let the game flow, but might just have overdone it on a couple of occasions.
Olympiakos almost respond straight away as Machado gets away down the right, but Szczesny gets just enough of a touch to the cross to keep it away from those in red-and-white before the ball is scrambled to safety.
GOAL - ROSICKY! Arsenal have the lead. Gervinho wastes one good chance, but gets back on the ball and gets to the byline before cutting the ball back for the advancing Rosicky to stroke home from 16 yards. Nicely done.
Wasted chances at both ends as Arsenal fail to capitalise on a four-on-three break, before Olympiakos similarly fluff their lines when Abdoun's low cross evades everyone and rolls out for a goal-kick. Needed someone in red-and-white to gamble.
Poor decision-making from Ramsey here, holding on to the ball in the Olympiakos area when he had Gervinho in space. Ramsey eventually crowded out, and Olympiakos bring the ball clear.
Jenkinson heads the ball clear and then heads off on an impressive run down the right that takes Arsenal into Olympiakos territory.
Good work from Gervinho, tracking the overlapping run of Diakite and snuffing out any possible threat.
Arsenal have lost much of their early control and tidiness. Olympiakos starting to grow in confidence and ambition.
Frustration for Arsenal here as the referee plays advantage after a foul on Gervinho, and then awards Olympiakos a free-kick for a foul by Rosicky.
Meade just guilty of trying to overplay here when the time might have been right to just get rid. Olympiakos get the ball back but don't punish the youngster.
Diakite's cross from the right evades everyone in the centre before Jenkinson clears. Good spell for the home side, though.
Wonderful run from Abdoun, spinning out of a tight area and beating two defenders before playing in Torosidis, who blazes wastefully over the bar.
Arsenal caught square at the back by a one-two that ends with Abdoun curling a shot goalwards. Szczesny on hand to beat it away for a corner.
Ponderous play from Chamakh rather wastes a good position when it looked like he and Gervinho had a two-on-one break going.
Shaky couple of minutes for Olympiakos, who are looking to slow things down and regain a foothold with some patient passing at the back.
Chamakh races on to a long ball and knocks the ball past Carroll but overhits it and can't keep it in.
Glorious chance for Arsenal! Great run from Oxlade-Chamberlain, whose cross is nodded back across goal by Chamakh and drops invitingly for Ramsey who completely misses his kick from 12 yards. Should've scored.
Bit of nonsense here as Rosicky is clearly hauled down by Maniatis 20 yards from goal, but the referee gives nothing and motions for the Arsenal man to get back to his feet.
Coquelin plays in Chamakh, but he's wrongly flagged offside. No damage done, Carroll off his line smartly to gather.
Chance for Olympiakos! Abdoun is played in on the left, but his low cross is smartly dealt with by Vermaelen at the expense of a corner, which comes to nothing.
Poor from Abdoun. His inital delivery is scuffed and cleared back to him. Given a second chance to put a meaningful delivery into the Arsenal area, he again scuffs the ball in low and Rosicky clears.
Two good positions for Arsenal in the space of a few seconds as first Gervinho narrowly fails to play in Chamakh before Oxlade-Chamberlain fires the ball across the six-yard box when he should perhaps have gone for goal.
A smart, patient build-up from Olympiakos comes to nothing as Abdoun's shot takes a deflection that makes things easy for Szczesny.
First touch for left-back Meade, a sliding tackle at the expense of a throw. My only other observation at this stage is that he is a tiny man.
Decent early move from Arsenal as Gervinho and Rosicky link up down the right. Olympiakos seem to have snuffed out the threat, but Oxlade-Chamberlain wins the ball back and tees up Gervinho, but he slices wide of the target.
Carl Fletcher: 'Think we'll surprise a few people tonight and grab ourselves a draw (1-1). Coming 2nd in the group isn't a disaster as there's no easy games from now. The league MUST be the priority so glad we've rested a few players! Welcome back ROSICKY!'
The latest from Sky Bet: although they've already secured their passage to the second-round, Arsenal (3/1) have fielded a relatively strong side in a bid to snatch top spot in Group B. Despite this, hosts Olympiacos are odds-on (4/5) to hand the Gunners a second defeat on the bounce. Marouane Chamakh and Gervinho have a point to prove up front, with the former 5/1 to score first and the latter 11/4 to score at any time. Former Manchester United keeper Roy Carroll has enjoyed a new lease of life in Greece, and the hosts 9/4 to win to nil.
Robson: 'In our last game we weren't strong enough in attack or in defence, Swansea were dominating the midfield. Tonight I feel with Chamakh up front we should win most of the balls going up in the air. I think with The Ox on the wing he has got the pace to beat their full back and swing the ball across to Chamakh who will win it in the air and hopefully get a powerful header on goal. I'm a bit wary of Squilaci playing at the back but I do think Vermaelen will help out in that area. I am extremely excited about tonight's game.'
'Seven changes to the team from the weekend is a good idea,' says Karl Wilkins. 'If that team couldn't beat Swansea at home then they will struggle with Olympikaos away! Key players like Cazorla need rest! Good team selection.'

Plenty of big names left at home by Arsenal for this one, and the Gunners have made seven changes from the weekend defeat to Swansea. Their team is: Szczesny, Jenkinson, Squillaci, Vermaelen, Meade, Ramsey, Coquelin, Oxlade-Chamberlain, Rosicky, Gervinho, Chamakh.
Good evening, and welcome to our live minute-by-minute coverage of tonight's Champions League clash between Olympiakos and Arsenal. The Gunners have safely secured their place in the last 16, but still have their eyes on securing top spot. They'll need a favour from Montpellier against Schalke, though, and we'll keep you up to date with that game as well.
