Only Grujic is ready for prem and that other lad Wilson but I think he went somewhere already, the others are raw and need a lot of game time so I prefer they played in the championship. I also think keeping Grujic around would be a wise move because he can give us depth in cup games.
I agree, I think Grujic is ready now, he had a decent season at Cardiff, so could at least play in the cup games and be on the bench, Ox is out all season, with Can going, he would be good backup for Fabinho as a DM,
