We've made, what, a ?35 m bid for Suarez? The club won't have any problem bidding up to ?45 m when it's Fabregas. Considering the money Barca owe us for him, we would pay at least ?5 m less then any other suitors, not to forget that there could be another clause in there somewhere such as a sell-on fee which was what was rumoured in the past. Man Utd definitely aren't paying that much regardless.
Fabregas isn't going to Man Utd to play for David Moyes over his father anyway. It could be different if Ferguson was there, but now every lure they have is gone. Anyone with eyes can see the loss of Ferguson alone will cause them to fade.

What does he gain from United by going to play with David Moyes?
Barca's asking price isn't ?30 m
. They'll demand ?35-40 m minimum that's how much they paid for him.
