Full time: Atletico Madrid 1-0 Arsenal (2-1 agg) Diego Costa's goal in the third minute of first-half stoppage time sends Atletico Madrid into the final, in which it will face RB Salzburg or Marseille on May 16 in Lille.

77': Atletico controlling possession and getting some good chances too. But it hasn't been clinical in the second half, else complexion of this tie could be a lot different.

67': CHANCE! Griezmann, who assisted Costa for the first goal, has a chance to score himself following some good work by Costa this time. Costa picks out his French strike partner from the byline and Griezmann has enough time that he takes a touch and picks his spot. His shot though gets blocked and pops up in the air for Ospina to catch calmly and diffuse the situation.

61': Impressive work rate from Mesut Ozil to hound the Atletico defence and win the ball back first. He then races through on the left hand side and could have had a shot himself. But he flashes a cross across the face of goal but none can get on the end of it. Arsenal finding joy down its left though!

58': Chances are coming thick and fast and the match is a bit stretched! Arsenal committing men forward is leaving huge spaces for Atletico to attack into after a turnover. Arsenal too, has had a couple of good chances that it hasn't made the most of.

54': CLOSE! Diego Costa could have had three goals in a matter of six minutes. The latest chance was probably the easiest. He was one on one with Shkodran Mustafi after some good work on the right flank by Thomas Partey. Costa dummies the sliding Mustafi and sets himself to shoot, doesn't get the right contact and scuffs his shot.

52': CHANCE, for Arsenal! Aaron Ramsey could have put Arsenal level, but fails to get over the bouncing ball and his shot is wide. Jack Wilshere's wild effort from outside the box fell kindly to the feet of the Welshman, who seemingly had an easy chance to convert.

49': CHANCE! Diego Costa is left unmarked at the far post and he keeps his header off a corner on target, Ospina catches the tame effort.

Half-time: Atletico Madrid 1-0 Arsenal (2-1 agg)

45 + 3': GOAL! Diego Costa (Arsenal's nemesis) applies a left-footed finish to put Atletico Madrid in control of the tie. The move began with a clearance from Jan Oblak. Griezmann then got on the ball and under pressure from Arsenal defenders, played the ball onto the path of Diego Costa, who took a touch and tucked away the chance confidently!

37': Koke's left-footed volley from outside the box has David Ospina scrambling. The Colombian didn't have to make a save, though, as the ball drifts wide. A good attempt though!

34': A brief spell of Arsenal possession with Atletico forced to defend deep. Chances, even half-chances, have dried up in the last 10 minutes.

24': Arsenal slowly working its way into the match. Attacking predominantly Atletico's right hand side, a couple of decent opportunities have popped up. Both teams though, lacking sharpness in the final third.

15': Arsenal struggling for rhythm but thankfully, Atletico hasn't yet made its early dominance count. The onus is on Arsenal to cancel out the away goal it conceded at the Emirates.

9': Substitution: Laurent Koscielny has picked up an injury and is being replaced by Calum Chambers.

6': CHANCE! The combative Costa wins a loose ball in the Arsenal half and gets a head start on the defender. He has plenty of space and could have done a lot better with his attempt. He fires over from the right hand side of goal. Arsenal let off the hook!

4': Atletico Madrid has started on the front-foot, playing higher up the pitch than usual. Arsenal has yet to get hold of possession, having kicked off.
