He isn't an Evertonian though! He obviously was once. I do not see any way as to how he improves us. A younger version yeah of course, but not now. he is no different from a Rademel Falcao or a Fernando Torres, great players back in their day but I wouldn't want them now.
If he stayed where he was or moved elsewhere then no I don't have a grudge, if he comes back then yes I do. he moved for his career, fine, he now wants to come back once his career is over and he has done everything he wanted to do. Brilliant. lets put a massive banner up of him on the side of the main stand for our massive evertonian overlord. In fact sod it, lets name the new stadium after him. He deserves it after him deeming us worthy of his abilities for a season or two after his proper career has finished.
