Kjaer apparently has a release clause of 10m pounds...we need to pay that up, let him finish this year with palermo and get him at juve in the summer. If we don't pay that for this future talent then we would be crazy. The idea of him and chiellini is mouthwatering.
I do like the kolarov idea, that means 2 of molinaro, de ceglie, or sali would (should) go.
My guess figures:
Spend 10m on rafinha, kjaer, and kolarov plus 15m on a new striker. That's 45 million minus sale of grygera 5m, molinaro 4m, and 6m from trez (if he isn't on a free, not sure of his contract). So that's for new great players for 30m....
