All sorts of shenanigans going on inside the penalty area as Gabi prepares to send a free kick from the right into the penalty area for Atletico. Referee Pavel Kralovec shouts at everyone, no one listens, the cross comes in and Bernd Leno gathers. All a fuss about nothing.

Here we go again at the BayArena. How important could a goal for either side prove?

Must do better will be the message from Atletico boss Diego Simeone. Bayer Leverkusen will be disappointed they have not capitalised on their dominance though.

Atletico can't believe they aren't ahead. From the resulting corner, Tiago launches himself into an acrobatic volley but his low strike is brilliantly turned away by the full-length Bernd Leno. You won't see many saves better than that.

A rare attack by Atletico sees Mario Mandzukic's 18-yard volley deflected out for a corner.

Not a chance. Wendell goes down with a few pirouettes inside the penalty area but Juanfran clearly gets the ball for Atletico.

Bayer's physical approach is certainly taking its toll on Atletico as Diego Simeone is forced into his second change before half time. This time, Saul Niguez lumbers off - having not recovered from the earlier knee to his back - and is replaced by Raul Garcia on the left of midfield.

A shock could be in the making at the Emirates as Monaco take the lead through Geoffrey Kondogbia. Danny Welbeck loses possession and the visitors attack with speed, Joao Moutinho squaring a ball to the unmarked Kondogbia, who shoots from more than 25 yards and his effort flies into the back of the net via a slight deflection off Per Mertesacker.

Left back Guilherme Siqueira can't shake off an early knock ansd is replaced by fellow left back Jesus Gamez.

The change doesn't seem to do the visitors any harm as they are inches from taking the lead just seconds later. Arda Turan lobs the ball over goalkeeper Bernd Leno at the stretch but the stopper recovers just in time to finger tip the ball away from Antoine Griezmann's head.

It's not often a Diego Simeone team gets out muscled but that is just what Bayer Leverkusen are doing to Atletico so far. Kyriakos Papadopoulos goes too far though as he is booked for a very meaty challenge. This game could get tasty.

Most of the action so far is at Bayer Leverkusen's end. Atletico just can't get hold off the ball.

Atletico are all over the shop at the moment but a lot of that is down to Bayer's high pressing game. This time Karim Bellarabi whips in a cross from the right and Miguel Moya just about palms the ball away from Josip Drmic's head. All Bayer so far.

A stunning strike from Emir Spahic deserves better. The hosts' defender unleashes an absolute thunderbolt past goalkeeper Miguel Moya from 25 yards but it cannons off the bar to safety. Strike.

Saul Niguez is in the wars for Atletico as he gets a boot in the back. The stretcher bearers are primed but, are waved away, as he limps towards the sideline. Treatment will continue.

A look of concentration on Diego Simeone's face as he watches intently from the sidelines. Even when he doesn't mean to, he looks scary... You wouldn't mess would you?

Another corner for Atletico and it again comes to nothing despite a bit of a scramble.

Not very is the answer going by that. They take it short and the chance is wasted.

A sloppy start by Atletico but persistence by Arda Turan near the corner flag has earned them a corner. We know how dangerous they can be from here...
