The Marseille goalkeeper still believes that his side can qualify from a group also containing Napoli and Borussia Dortmund after missing vital chances against the Gunners
Andre-Pierre Gignac, Mathieu Valbuena and Andre Ayew all went close as Elie Baup's men dictated the play for large periods but the Gunners proved more clinical, Theo Walcott and Aaron Ramsey netting before Jordan Ayew's late penalty reduced the deficit.

"These kind of games hinge on the small details," he told Canal+. "It's infuriating, because it was not a bad [performance].
"Before the goal, we had not conceded too many opportunities. It is what often happens in the Champions League. Now we must continue. This is not done."
However, Valbuena lamented the individual errors that he felt cost Marseille at least a point.
"It was said at half-time that, if we cannot win, we must not lose," he explained. "It's a shame because we had more chances than them.
"This is the top level; errors will be punished. We have already experienced it. We feel we can win but in the end we did not win."
