The fact that Marseille was in complete control and the players just seemed off. We were lucky, imo, that we didn't conceed. I think the players would be more burnt out running after the ball because they didn't have the possession. To be fair, i think we should have made attack better, and that we showed some weakness down the right hand flank no and then and even the right winger had to come all the way back to help defend, making an counter attack even less strong. Like i said, if Zhirkov came off earlier that we would at least have more control in midfeild. EDIT: Oh and the constant switching off players in positions, imo didn't help either. Malouda in the right wing isn't as strong on his left, and Kakuta in CM isn't as strong either, and also tires them out more.
