We dont have to... Apart from Sancho, the rest are on relatively lower wages.
Rashford, maybe the club were giving him favourable terms because he is a academy lad and has done reasonably well on occassions.
Anthony... Imo if he only wants Betis... we can say we want 40m+, so you either get them to pay up or dont go to the world cup, we know how desperate he will be of that.
Sancho - probably the hardest one to get rid because football / WC is not a motivator for him
Garnacho - Same as Anthony, we dont owe him anything, if he only wants chelsea and we want 50m plus... then too bad.. miss the world cup. Again, after missing the last one, I am sure he is desperate for going.
We have to use the world cup as leverage... we need to tell these players and their agents... the longer it goes the higher the transfer fee becomes.
