Fergie said in his book that Arsene struggled to accept that his sides playing perfect football could lose, and that intensified their feud. Now, that might be Fergie trying to stir the pot but it doesn't contradict other impressions I've got about him, ie. being a "bad" loser, if you want to call it that. You might very well think that he isn't capable of delivering trophies or success because his philosophy is outdated, or his tactics are naive - you might very well think that. But I do not think for a moment that Arsene has become disinterested and complacent.
