I think it was the right time to move on from Wenger too, but I don't know if I had felt that way if his work with Sven had been given a chance. Ifs and buts I guess.
I reckon it does say something about how the club is run though when we hire Sven on the understanding that he'll work with Wenger only to sack Wenger four months later. Gazidis was one of the worst things to ever happen to us. He weaseled his way out quickly afterwards too so he wouldn't be held responsible for the damage.
