Isn't Sambou's contract running out anyways?
Does the youth teams have the players to play in the same style as what Silva wants, i.e. 4-3-3 or 4-2-3-1? Do they have the right type of wide forwards?
And yeah, the gulf is massive. Remember we have several under 23 players in the first squad (DCL, Davies, Lookman, Kenny, Richarlison. Imagine how they would dominate at this level. I would imagine the lads that have been on load to Championship have a much better chance. I.e. Connolly, Williams, Robinson, Holgate) and at best they will most likely be in the periphery. If there was no transfer budget then I cold see some of the promoted to the subs bench.
