What will (probably) happen:
Transfer problems with the loan endings (Meslier, Harrison, Helder Costa, Augustin, White)
Costa has a pre-contract agreement
Brighton will ask for an unpayable fee for White + big teams join
Meslier and Harrison will join if their clubs get the money they asked for
Big teams will push for Kalvin Philliphs

What would I do in the market:
Get Meslier and Harrison immidiately before they could go anywhere (may 12M)
Let Augustin go
Sell: Dallas, Klich, Casilla, Douglas,
Bring back James Milner for free
Get Juan Foyth from Tottenham, he will fall out of the squad if Mourinho buys defenders
Complete the deal with Robin Koch
Complete the deal with Habib Diallo
Berghuis maybe?

Money incoming: around 25M
Money spent: around 45M
