In Turkey they are saying an agreement is in place for Kolo to join Galatasaray (who mean business, Sneijder has signed, it's said Drogba is now a done deal, and Kolo on the agenda). The fee would be nominal, around £1.5million to £2million as he is out of contract in 5 months. But I think this deal would be dependent on us signing a new central defender because I can't see us allowing Kolo to leave without a new signing to immediately come in as we always seem short on defensive cover. A top club needs 5 central defenders of good quality I think. We have Kompany, Nastasic, Lescott, Kolo, and Micah (with Rekik on the fringes), but two of them are currently injured and one is away.
Perhaps it could go: Mario to Milan -> defender to City with some of that money -> Kolo to Galatasaray.
