I want him gone, a year ago tbh. The problem is him leaving now is not maybe the wisest idea, with the season upon us n' all. A new manager will not have sufficient time to make the changes. Let him stay the season and then leave at the end.
Wenger has been great for this club, but imo he has gone stale and the game has passed him by. Strictly from a football point of view, I no longer think he is capable to deliver any more trophies.
As thoroughly argued in this thread, the board must take their fare share of the blame but that in no way can excuse some of Wenger's decisions over the last few years:
1. Retaining the services of Eboue, Denilson, Manuel, Rosicky as long as he has done and back them to the hilt in the face of clear evidence to the contrary regards their contribution.
2. Persistence in playing players out of position, negating their effectiveness and in turn the team suffers. Bendtner, Theo, Arshavin, Eduardo, Eboue (flying right winger) all in attacking positions, all detrimental to our potency as an attacking force ...especially when the chips are down.
3. Knowing full well of our deficiencies in attack and defence ...going out and purchasing super quality like Squid & Chamkah, telling us they are actually football players. Those two transfers should be fully investigated.
4. Abject failure to coach the team defensive responsibility, when the ball is lost ..seems simple right, well it's not so!
5. Abject failure to consistently motivate the team, and instill a strong mentality especially when required in the big decisive moments of the season.
I could go on, but over the last few seasons he has made some bad decisions and failed in some basic requirements of his job for a coach befitting his status as a top manager, and this club's status as team expected to realistically challenge and win some silverware.
From a football point of view alone (i.e things under his control as manager), I think he's past it at the top level ...he's lost the edge required to a be champion again.
