Nope on this. On so many levels.If Bernardo were to leave this summer and we still intend to buy a LB (but not a out-and-out LB). Why not do something like this:
OUT:
Bernardo ~80M
IN:
Gvardiol (as LB) ~80M
Move Grealish to midfield and buy a left winger, options:
Neymar ~80M
Felix ~80M
I believe both are attainable this summer. PSG want to get rid of Neymar for balance in the team, Atleti need to sell to balance books + maybe to be able to buy Ronaldo from the rags?
