IMO 8 m salary max, and that is stretching it, as it should be lower tbh.
And yes i agree with all that s4cth said, Pogba is a walking disaster proffesionally speaking and i fear we will not be abel to recover. Even if by some miracle we recover him, i feel he is too much of a diva in the dressing room and the field, and would be troublesome to have a high earner like him, getting out of his prime and not being a fundamental piece on the team.
If he comes on a free and like 7m salary (im sure he will ask for more) we can talk.., but he is not worth more than that.
