We have three big players for potential swap or part exchange deals:
Pogba - Varane, DeLigt, Ronaldo, Valverde
VDB - Barella, Bastoni, Moriba, Dembele, Firpo
DeGea or Henderson are also big swap possibilities as links with Milan on Henderson and surely big clubs would be interested in DeGea even with those wages
Then we have others:
Dalot - Sod an extended loan, offer him cheap to Milan....Tonali, Kessie, Leao, Romagnoli
Lingard is an obvious one for Rice but possibly even JOnes, Matic, Mata, Pereira could be of interest....some of them coul even be offered to Villa for Grealish
Again Tuanzabe to Villa...Daniel James also
Brighton and bissouma alot of these players could be used as a bargaining chip
Martial may have interest from some big clubs....Spurs and Kane for example or again Madrid
Not saying I particularly want some of the players, but these are all credible examples
We actually have a lot of squad players and big players that can for differnt reasons be deemed surplus to requirements...I don tkno whow difficult these are to do, but is it any more tiresome or time consuming than having to sell them to raise funds?
