Did you see Wenger's post-match interview. He mentioned "character" (bingo) and "mental strength" (bingo) but it was rather half-hearted. He does know his team sucks. I don't think he accepts it's down to him just yet though, and TBH if there were more natural leaders in the team then Wenger's failings maybe wouldn't matter so much. As it is, the few leaders there are are surrounded by too many half-assed losers and that will wear anyone down eventually.
