In fairness your opening post said he won us 3 points,
I really didn't say that. I said he was "instrumental" in us winning three points. I don't want to split hairs, but you are attributing something to me that I did not express. He played his part in us winning that game, no more nor less than DCL, James, or Allan did. Given that I agree with much of what you say, I just want to clarify that so that there is no misunderstanding. Where I differ from you is that I feel he is not given the credit for when he does play well - and I believe he deserved a lot of kudos for his Spurs performance which was not simply a case of him "doing his job" no more than DCL scoring a hat-trick against Brighton was him "doing his job." It was an excellent performance, the level of which you will not get every week. However, his behaviour and erratic performances have made a rod for his own back, so this is largely on him.
I think he's probably on the way out at Everton because many of the fans are now implacably opposed to him. I'd have my doubts that he can play so well as to make them look foolish, so it's probably a matter of time now before he is deposed and shunted out. And another cock-up in the derby will spell an immediate end, I suspect. Let's face it, you wouldn't bet against it.
