Mass selling won't work, this isn't FIFA ffs you can't just bring in players and expect them to gel instantly.
At most I'd expect 3 signings, realistically 1 big one and a couple smaller ones. Not really sure why we're bothering to sign Xhaka now really, we don't need him next season and his clause starts in a year. To buy now is to spend £20mil more than his clause.
Priority HAS to be ST and RW for me. Lukaku and Mahrez would be ideal, but I can't see Mahrez forcing a move. Reus would be a dream too, but an unrealistic one. Not sold on Morata, not really a top goalscorer by any means. Maybe Ar is right on Lacazette, a strong punt as a winger or striker if not an incredible one. Ibra would also be a punt but a worthwhile one imo.
Being realistic though, I'd expect us to sign Gotze, a big team reject in a position already filled in our squad.
