Personally I think youngsters will get a chance next season such as Enes Unal, Patrick Roberts, Maffeo, Aleix Garcia and maybe Zinchenko, who have had good seasons. The reason why I don't think they've not been playing for us/shipped on loan is because we have too many senior members. Could you imagine how the likes of Zaba or Sagna would feel if a 19 year old was playing ahead of them. The dressing room would be unsettled. Maffeo and Garcia have shown that they can play a part this in this team, a good example being against the rags in the mickey mouse cup, Unal is banging goals in for fun and Roberts is having a good season too.
So next season I expect the youngsters mentioned above being in the team next season, as well as buying a few top quality players.
So next season I expect us to buy:
Ederson, a new right back with Maffeo as backup, Hernandez, Laporte, a new centre midfielder with Garcia as backup, possibly Isco with Zinchenko as backup and Mbappé with Roberts as back up.
