ESPN seem to report that we have a first option to buy back Fabregas at a fixed price which is quite close to the 25 million pounds Man U have offered. If he goes to any other club, we get 50% of the profits made.
If their reporting is true (I find this to be the most probable arrangement), then, Man United can go up to 35 million or whatever but we will have a bid accepted at 25 million only. I'll be quite satisfied and re-assured if this is indeed the arrangement.
In any case, I can't see him moving now that Thiago has left.
