In the first minute Yaya Touré goes down in the penalty area after a challenge by Christian Poulsen but the referee waves play on Photograph: Martin Rickett/PA

Just nine minutes in and City go behind to another soft goal from a set piece. Their defence fail to deal with an Ajax corner and when the ball comes back across the goal, Siem De Jong nips in to lift the ball over Joe Hart and into the roof of the net from the tightest of angles Photograph: Dave Thompson/PA

Eight minutes later some more slack defending allows De Jong to get his, and Ajax's, second. An inswinging corner goes towards the near post where De Jong is completely unmarked and guides a free header past Joe Hart Photograph: Alex Livesey/Getty Images

Halfway through the first half City get back in the game courtesy of a fantastic finish by Yaya Touré. A cross from the right falls to Touré at the back post and he chests down before volleying acrobatically past Kenneth Vermeer Photograph: Phil Noble/Reuters

As the game goes into the final 15 minutes, and with City still behind, Hart launches a long ball down the middle which is headed on by Mario Balotelli to Sergio Aguero, who lashes it home from just inside the penalty area Photograph: Alex Livesey/Getty Images

With just two minutes to go Aguero has the ball in the Ajax net again when he turns in Aleksandar Kolarov's cross, but the goal is ruled out Photograph: Lee Smith/Action Images

In the dying seconds the ball is pumped into the Schalke area towards Balotelli who is being manhandled by Ajax's Ricardo van Rhijn ... Photograph: Martin Rickett/PA

With Arsenal starting their game at Schalke in second position in the group there are not so many headaches for Arsene Wenger, though the Gunners need a result of some sort tonight to keep in control of their fate Photograph: Christof Koepsel/Bongarts/Getty Images

After 18 minutes Olivier Giroud surges into the Schalke box but is tackled before he can get a shot away. Theo Walcott picks up the loose ball, scoops it over the goalkeeper Lars Unnerstall and taps it into the empty net Photograph: Odd Andersen/AFP/Getty Images

Eight minutes later a diving Giroud makes it two. He launches himself towards Lukas Poldolski's superb cross and the ball whizzes into the Schalke goal Photograph: Odd Andersen/AFP/Getty Images

Just when Arsenal start to think that the game is over, Schalke striker Klaas-Jan Huntelaar, above left, brings them down to earth with a bump when he lashes home on the stroke of half-time Photograph: Odd Andersen/AFP/Getty Images

Just past the hour mark Podolski is in the clear and bearing down on the Schalke goal when referee Nicola Rizzoli calls play back after Marco Höger tripped and lay injured on the turf. The Arsenal players are livid Photograph: John Sibley/Action Images

Just four minutes later the inevitable happens and Schalke get an equaliser after Jefferson Farfan's shot is deflected into the net by Thomas Vermaelen.Final score: Schalke 04 2-2 Arsenal Photograph: Frank Augstein/AP
