Not sure they're underperforming like.
None of them are what you consider good players yet, massive potential with some for sure.
Currently we have :
Holgate, Lewis Gibson, that Dennis fella from Fulham, Henry, Vlasic, Lookman, the boy Robinson who just got a call up, Tom Davies, DCL, JJK, Beni, Dowell, Galloway, Browning, Pennington, Connolly
They are just the 1s off the top of my head, now granted some of those havent really kicked on with their loans so they might possibly be punted, but are we deeming all these lads now rubbish? We must be if people wanna sign loads more yoots to replace the yoots we already have.
