Why do you keep saying 4th?

We haven't finished 4th for 3 years.
The situation has changed so my opinion has changed, as has other people's, but he was getting a lot of stick back in the day from
some people. In the era where we were struggling to compete financially I think he did quite well to keep us "up there". Now the money is there so there is no reason we can't compete, he's been signing the sorts of players who should enable us to step up like Ozil and Sanchez and while the FA Cups were nice we really should be competing for the biggest prizes now. We're not, and that's why he has to go. I don't think Wenger is satisfied with us being 2nd best but I don't think he's able to do better. I blame the board too though because they ARE happy for us to be 2nd best as it keeps the money rolling in.
I'm not sure it will take that long to improve things IF we get the right manager in - note how Chelsea did so poorly last year when they had a manager the players couldn't work with, this year they'll probably be champions.
As for Wenger not taking the blame for things, that sounds like a lot of the managers who you look at admiringly. You do this sort of thing a lot, you hold people to different standards depending on whether you like them or not.
I hope Wenger goes at the end of this season, if he does he'll go with some dignity and most people will respect what he's done for the club.
