We actually wanted him to sign a new contract but he chose to leave for a club where he felt he would play every week. Not that I have a problem with that but it’s madness to think football fans won’t have a go at an ex-player for joining a hated rival.
If he wants to go clog their squad and their wage bill for the next 5 years whilst contributing very little else then he does so with my complete blessing and I shan't be pretending to be upset about it.
