I think he is willing to change. Moyes changed his ways too, but importantly that summer Moyes was able to move on particular players who had obviously become a disruptive influence. Obviously Rooney went, who had outlived Everton and Radzinski went having made some quite snide remarks. Linderoth and Gravesen also moved on.
I don't think it is just about a change in style. I think some of the experienced players have lost faith with Martinez. Mirallas's reaction on Sunday told a story. Like with Rooney, when you have a player who thinks they are too good for the club it can have a very corrosive influence. I suspect Mirallas, alongside Distin and Etoo have lost faith in Martinez's abilities.
Martinez does need to change (I feel he has done) but he also needs to move 3-4 on in the summer and find people who want to play for the club. The frustrating thing is, he has bought some really good young players, and brought along some others.
Barkley, Stones and now Garbutt have really made an emergence under Martinez. Lukaku, Besic and McCarthy have done all been good signings. When you throw in the likes of Coleman we have as strong a nucleus of good players as we have had for a while. This is down to Martinez himself and gives me some cause for optimism.
