Squad is too big, I imagine you forgot about Gundogan, which if added would make your squad 30 players.
For example, if Dinho, Toure and Delph are your CDMs, of which we play with only 1, then Aleix is better off being loaned out.
It's possible I misunderstood your naming of these players, are you saying you want Angelino and Maffeo in the squad as backups to the other fullbacks, or you want them in the squad in the future? Because with 4 fullbacks they would get no playtime, Maffeo could replace Alves after he leaves.
