Bellingham would be a ginormous waste if you play him as a 6, it will be Pogba all over again.
I throw up in my mouth a little bit as I'm typing this but for 100m English player to be a Casemiro successor, I'd rather Declan Rice - who I don't rate all that much, if we decide to spunk that money.
Caicedo is a name that has been brought up a lot in these discussions but looking at Bissouma at Spurs, I do have reservations about his ability with the ball. Hopefully our revamped scouting system can surprise us with an unknown gem somewhere.
