Well we have three very tough fixtures for Wenger at completley the wrong time for him
Wednesday in Munich, Then in 2 and a half weeks away at Anfield (with only Sutton in between) and then the return leg at home to Bayern.
Fails to win all three of those games and i think the ledge falls away from under his feet, yes only he decides his future but he knows deep down he has to justify even to himself a contract extension (thus why he waited until after the fa cup in 2014 to sign an extension, i actually believe he wouldn't have signed an extension if we hadn't recovered against Hull).
