Like who? Other than Ferreira and maybe Ferdi and Marmoush, I think we've done a pretty good job of scooping up the players that have options and this is one of the reasons we're talking about a Golden Generation.
Ferreira is the only one that makes the starting 11(if not injured!) and that's only because our backline is shambolic(CB Cornelius + whoever is not equal to what we are putting out at other positions).
Ferdi has so much potential he would be great to cap(if actually interested), but I would be doubtful of him coming over to play the junk teams we will have in our pool. He is likely able to make the dutch team and tbh his Canadian ties are tenuous anyways.
Marmoush is interesting as well, but he doesn't play much and hasn't scored in Bundesliga. Maybe he would be a good call up vs a minnow because for the reserves he scored fairly often. I just don't see him as a huge part moving forward what with all the other attacking players we already have coming up.
