You don't think Madrid would already have got him if Levy would sell for £50 million?
Earlier in the summer I made a similar point, however as time wears on, it's clear that Levy isn't going to be forced into selling for an "average" sum. He's going to milk Madrid for every last penny he can get, and fair play to him for doing that - it is his job, of course.
He'll end up going for close to the fees being reported in the media. I don't think he's worth that though, and I would hope that if he were available for somewhere in the region of £50 million that we would have made our interest known to Spurs too.
