Unless I'm totally getting this wrong there's absolutely no reason why they'd swap players. They need to make money to balance the books. If they buy Caicedo and we do get players in it'll be seperate but agreed transfers.
Better to sell Moises but agree to sell Colwill at xx millions than swap...
No more loans please. Colwill was great but the charade after is pointless. Either players want to join a better run team, higher in the league, and playing in Europe or they want to stay at Chelsea.
