I'm not sure that what 'Fab' Romano thinks we should get for him holds any more weight than what I think to be honest, but that doesn't really change the point at hand. I can't see it myself but if we got that much for him then even better, it's even more money we can reinvest.
I don't see Keane going. Forgetting my own opinion and just basing it on the way things have gone under Ancelotti, I'd be very surprised if we moved him on. As I said, I can imagine it being Mina or Holgate, I just thought Holgate was a bit easier to assign a value to so I used him in the example. The number of clubs who could match Mina's wages is small, the number of clubs who could match his wages and are at the sort of level where he would be seen as a good signing is smaller still. With Holgate, leaving aside that it's a bit of a stretch to say he covers all 4 positions, I'm just not sure that would be all that relevant. Godfrey basically offers that too if it was needed, but with a new right back and Coleman unlikely to be going anywhere I don't really think it would be a sensible move to hold on to him just on the off chance that you might need him to play full back if 3/4 other players were injured. There's also the matter of whether he'd want to stay to be honest. I just don't see him ever being a key player here, and if he sees it the same way he might think the time's right to try his luck elsewhere. He'll have been here 6 years and be turning 25, he's about to come out of the 'promising' category and into the 'bog standard PL journeyman' category if he doesn't make a position his own soon.
I'd be very surprised if we signed a first team centre half. I think there's probably 5 positions that we actually need players for, adding to that list by selling our first choice players in another position would seem like leaving ourselves an awful lot to do I think.
