I put this in the Haaland thread but probably better here.
If you have a budget of approx 80 million as mentioned above, I think you could have a great summer and completely turn the squad around.
Sell:
Martial - 40 million
Pogba - 60 million
DDG - 20 million
That gives you 200 million to play with, plus may 10million for Dalot another 10 for Jesse, 5 for Chong and 5 for Pereira gives 230 million
Sancho 70-75 million
Haaland 100 million
Rice 50-55 million
Henderson
AWB Lindelof Maguire Shaw
Rice Bruno McT
Sancho Haaland Rashford
With a back up:
Pereira
Williams Tuanzebe Bailly Telles
Matic Fred DvB
Amad Greenwood James
You'll still have Cavani, Jones, Mengi, Shoretire, Pellistri and Garner
Ben White is another option instead of Rice, as much as I'd hate to lose him from Brighton, he plays very comfortably as DM or CB in a two or a three, so could work as extra CB cover as well.
This probably an FM approach to things but what a trio that would be to sign!
