I literally have no idea how you get that from Dein talking in 2014 saying how they go (present tense) out after every (i.e, not a one off) home game.
Zim also said something above about him not being desperate to win at all costs and, for once, I agree with him. But I don't think that's a bad thing, and I don't think he ever was like that. I don't think I'd want a manger who is - Mourinho is like that and while he tends to achieve short term success he usually leaves a train wreck behind. I do think Wenger is too much of an idealist and wants to do things the 'right' way, if he was a bit more pragmatic we'd probably have won more over the last decade.
He is what he is and my take is he's always been like this. Maybe he's lost a little bit sharpness, he is getting older, but I don't think he's radically changed since he came to us. In fact, if anything that is one of the problems. Football has changed around us and Wenger hasn't been able to adapt and keep up. Which doesn't mean everything he's done everything wrong but the things which gave us an edge aren't there any more, now everyone uses the same or better fitness regimes, everyone has a worldwide scouting network. Wenger's USP isn't so 'U' any more.
Bottom line, to suggest he's indifferent to defeat is ludicrous. I refer you again to Dein's comments, they surely carry more weight than us speculating about his body language.
