$#@! em'
if we sell Pogba

It's Cavani, Verratti and then we buy a good LB and trequartista/SS.
That's my view.
If we sell to PSG, Verratti is a must. Usually when you sell its at a premium so the players we receive should not be at a premium.
Verratti (35 million), Cavani (35 million) = 70 million EURO
He's worth 120 million IMO so I'd want another 50 million EURO.
It's a steep ask, but if a bidding war ensures (and I'd fully encourage disclosing all bids if one ensures), we should be able to obtain a massive overpayment. We should also include Rabiot just for lulz.
You then use part of the the remaining 50 to buy Christian Eriksen, and remainder to pay the increase in wages. You could also add a fullback as well if one is obtainable.
-----Cavani---Tevez--------
-----------Eriksen----------
Vidal-----Verratti----Marchisio
Depending on the team who we sell to I'd ask for a similar package, but I do believe PSG will pay the most given his French heritage, and they have the most attractive assets that they'd give up. I mean who would we get from City that they would "sell". Same with RM.
