My suggestions to the board is going Cancelo, minum air, Danny Rose, and Belotti.

Cancelo - Oxlade will stay with Arsenal, Aurier to Spurs already
Minum air - HG, overpriced but we must spend the money or else we aint got no midfielder in Spurs game.
Danny rose - Chelsea will bid for him after the derby match in Wembley for Alonso competitor.
Belotti - He can replace Costa. Superb header and positional awareness.

Costa can eff-off to Atletico for what i'm aware. Go training with Atletico and never come back Diego.
