Yes he has done well with the team he has got but he could get almost any player if he paid that little bit extra instead of buying or extending contracts for crap like Squillaci, Santos, Gervinho, Denilson, Djourou and Bendtner who were on 50k plus a week. Denilson was the highest paid player in Brazil got paid more money than Neymar before his move to Barcelona.
It was touted that David Moyes was in the running, as he has managed Everton on a shoestring budget but it will be Wenger who will choose to leave or not and not by the choice of the board, also it will be Wenger who will appoint the next manager (probably Dragan Stojkovic) as the board does not have a footballing brain between them ever since David Dein left.
Although I like the Ozil signing we needed an experience goalkeeper, centre back, defensive midfielder (Flamini was pure luck) and a striker before an attacking midfielder, no doubt Wenger think's our weakness is the final ball rather than having only three centre backs which one is a long term injury and only one out and out striker (Giroud) not counting Mr 52K Nicklaus Bendtner.
