It's all over and Diego Costa's late header means Atletico Madrid will take a 1-0 lead over AC Milan to the Vicente Calderon for the second leg of their Champions League last-16 tie.
A foul by Adrian Lopez on Taarabt earns him a yellow card but the resulting free kick comes to nothing.
A very lazy - almost deliberate - trip by Rami on Costa a few yards outside the box gives Atletico a dangerous free kick and earns the Milan player a yellow card.
Milan simply haven't offered enough of a forward threat in this second half to trouble Atletico and it looks as though they've spurned their home advantage.
Rami unleashes a ferocious strike which is far better than anything Balotelli produced during his time on the pitch tonight but the ball whistles just past the post.
It didn't look like a goal was coming despite Atletico's toothless pressure but eventually their patience pays off and it's hard to see a way back for the hosts now. They can't really afford to head to Spain with a deficit to overturn.
GOAL COSTA! Gabi's corner is flicked high into the air by Abate towards the back post, where Costa is lurking to plant a firm header into the net.
Atletico are enjoying the wealth of possession at the moment and use it to win another corner on the right.
Adil Rami weighs in with a well-timed challenge to prevent Insua from delivering a cross on the left wing but he does concede a corner.
To say this game is heading towards a goalless draw is an understatement. There's been very few chances throughout this second half and to be honest both sides look more than content with this scoreline.
Garcia receives a pass on the right side of the box before blasting a low shot straight at Abbiati, who never looked troubled.
Gabi hoists a high ball into the box but Costa's volley from a very tight angle on the left side of the box is cleared.

Emanuelson chases Balotelli's pass down the left wing but Juanfran wins a tackle to concede a corner.
Essien's cross on the left wing finds its way to Taarabt on the right side of the box but he scuffs his shot and Atletico can clear.
Balotelli draws the foul from Costa around 25 yards out and the Atletico striker is shown the yellow card. He can have no complaints.
Neither side are willing to take any attacking risks which could leave them exposed at the back so it's very hard to see any goals being scored in the remainder of the match.
Emanuelson's corner on the right picks out Essien but the midfielder's glancing header goes wide of the far post.
De Jong is fouled by Garcia and AC Milan have a free kick in a central position which they'll look to send into the box.
Atletico continue to press and win a corner down the right wing which comes to nothing after a poor cross from Koke.

Referee Pedro Proenca of Portugal blows his whistle to bring a fairly entertaining half to a close, with both sides still level at 0-0.

The ball breaks for Balotelli on the left edge of the box but the former Manchester City striker's curling effort goes wide of the far post.
Taarabt's cross is cleared but AC Milan get possession back again quickly and look to attack once more.
Quick feet from Balotelli helps him beat Miranda on the right wing so Suarez weighs in with a rather calculated foul to stop him entering the box. A yellow card is shown.
Turan is down clutching his ankle but no foul was given against de Jong so it's down to AC Milan to sportingly kick the ball out of play.

That said, the patient approach nearly pays off when a low cross towards Costa is nearly prodded into his own net by Abate.
Emanuelson loses possession cheaply in midfield but Atletico are once again too slow to get forward.
Play continues without Balotelli for the time being but he's able to return to the pitch when his side win a free kick in midfield.
The game comes to a brief halt after Balotelli takes an accidental arm to his nose from Miranda. He should be fine to continue though.
AC Milan are certainly carving out the best of the opportunities so far and although it's still 0-0, they'll feel confident more will come their way.
Balotelli controls the ball down the right side of the area before an unexpected backheel picks out Kaka, who drives a shot from a narrow angle over the bar.
Koke produces some lovely close control to beat Kaka in midfield but his final pass into the box is disappointing.
Diego Costa slots a clever pass down the right wing for Juanfran but the low cross which follows evades his team-mates.
The visitors are enjoying a good spell of possession but AC Milan are content to sit back and deny their opponents are killer pass.
AC Milan are forced into a change with the limping De Sciglio, who is still feeling the effects from that earlier foul from Insua, being replaced by Ignazio Abate.

Tempers flare up after Emiliano Insua chops down Mattia De Sciglio on the right of midfield. A yellow card is shown.
Adel Taarabt receives the ball on the right edge of the box before sending in an inch-perfect cross for Andrea Poli, whose downward header looks certain to find the bottom corner of the net only for Courtois to produce a stunning save to turn it onto the post.
Despite players waiting for a long ball into the box, they play the ball short and it isn't too long before the move breaks down completely.
All of a sudden the game bursts into life when a rasping drive from Kaka on the edge of the box crashes into the bar after a brilliant finger tip save from Thibaut Courtois.
Juanfran makes a forward run inside the box but Koke's pass goes straight through to Christian Abbiati.
Balotelli brushes himself down to take it himself but his ambitious effort goes well wide of the post.
Both sides are content to keep possession without any real urgency to get forward and create genuine chances.
So Atletico have probably edged the early exchanges but the pace of the game has dropped markedly in the last few minutes.
Juanfran whips in a dangerous cross from the right but a diving Garcia can't quite jump high enough to make connection.

AC Milan get the action under way in this Champions League last 16 first leg against Atletico Madrid at the San Siro.
Both sets of players make their way out onto the pitch in front of a packed house at the San Siro. Can the hosts respond to the cracking atmosphere being created by their fans tonight? Or will the class of Atletico's strikers ultimately prove too much?
By contrast, AC Milan have struggled domestically and are down in ninth place in Serie A, 31 points behind league leaders Juventus. Nevertheless, Atletico star Diego Costa said yesterday: 'In order to achieve something positive, we will need to do our best. Milan have a lot of tradition and know how to play these type of games. We will have do a great job against them.' On Mario Balotelli, he added: 'Balotelli is one of the best strikers in the world. Our defenders know this and will keep a close eye on him.'
The Spaniards arrive at the San Siro having bounced back from their second league defeat of the season at Almeria by beating Real Valladolid 3-0 on Saturday night. That was Atletico's third victory in four league games and lifted them level on 60 points with Barcelona and Real Madrid at the top of the Primera Liga.
Adam Gillis makes a very good point. He writes: 'Just like last night, Milan's experience in the cup will see them past Madrid, 2-1 home win.' I think it's easy to forget how much experience of playing at this stage of the competition counts, and Barcelona certainly used their know-how against the relatively inexperienced Manchester City last night. A similar story tonight perhaps, regardless how talented Atletico obviously are.
Matthew Goodwin-Freeman writes: 'Can't wait for the match! I think Atletico Madrid will just be too good tonight, and am easy 3-1 win is coming! I just don't see AC Milan winning tonight! But let's see what will happen! Good Luck to both teams!'
