He's changed agents several times since signing that deal for £130k a week. Nobody put a gun to his head, but reading between the lines the leeches and hangers-on have done very, very well out of him committing his long-term future to CPFC2010.
He's gradually realised he's been held back by a small club which (by completely pricing him out of the market) has ensured he will have spent an entire career in utter mediocrity, with no chance of ever winning anything. In fairness his talent probably deserved better, but he's shackled in a loveless marriage of convenience and its too late to do anything about it now.
I can understand him signing the deal, but to sign it without any get out clauses is mind blowing.
Someone must have said to Wilf, words to the effect of:-
'Don't worry we won't stand in your way, you have my word'.
