Didier Drogba takes the ball around the dispairing dive of Bernd Leno but the angle that is created is too tight and his shot can't find the target Photograph: Joern Pollex/Bongarts/Getty Images

With 12 minutes to go Leverkusen get a big let off when the referee turns down a Chelsea penalty appeal. Drogba goes down in the area under a clumsy challenge from behind by Lars Bender but the referee waves on Photograph: Christof Koepsel/Bongarts/Getty Images

The game goes into injury time and just when Chelsea must be thinking "1-1 will do" Leverkusen's Manuel Friedrich soars highest in the box and puts a header goalwards ... Photograph: Martin Meissner/AP

2-1 it finishes and you can tell the Chelsea players aren't happy about that and the fact their poor run of results is continuing Photograph: Christof Koepsel/Bongarts/Getty Images

Such is the joy at the victory that puts Leverkusen at the top of the group, that winning goal scorer Manuel Friedrich grabs the megaphone and indulges in a bit of a sing-song with the fans Photograph: Christof Koepsel/Bongarts/Getty Images

Alex Song on his amazing mazy run which started just inside the Dortmund half and finished in the penalty area after he waltzed around half the Dortmund side. He then dinked over a cross towards the far post ... Photograph: Mike Hewitt/Getty Images

Van Persie doubles the lead with four minutes to go. Again he is wating at the far post, this time he stabs the ball home after Thomas Vermaelen flicks the ball on from a corner. Shinji Kagawa gets a consolation goal for the visitors during injury time but Arsenal win the match 2-1 and consequently qualify for the last 16 with a game to spare, and as group winner to boot. Now that surely must give Arsène Wenger something to smile about Photograph: Glyn Kirk/AFP/Getty Images

Yep. Zlatan's looking good ... Photograph: Alessandro Garofalo/Reuters

You would imagine there would only be one winner if Ibrahimovic and Barcelona's Javier Mascherano go up for a header Photograph: Olivier Morin/AFP/Getty Images

It's a surprise Milan's Kevin Prince Boateng doesn't hurt himself during the goalscoring celebrations after he makes the score 2-2. Unfortunately the joy only lasted five minutes as Xavi wins the game for Barça just after the hour mark Photograph: Stefano Rellandini/Reuters

Over in Russia the Zenit St Petersburg fans are up for the game against Apoel Nicosia and have gone flare crazy ... Photograph: Anatoly Maltsev/EPA

If you look really hard you can just make out Zenit St. Petersburg's Konstantin Zyryanov amidst the smoke from the flares. Apoel Nicosia withstood an onslaught from the home side but Zenit couldn't find a way through and the game finished 0-0. The point meant that the Cyprian champions secured their place last 16 with a game to spare.

There's a bit of a visibility problem too over in Minsk where Bate Borisov are taking on Viktoria Plzen, this time it's not due to flares but good old-fashioned fog Photograph: Sergei Grits/AP
