Why not?
We are playing 1 game a week all season effectively and Bentancur returns in a couple of months, that's 5 midfielders for now and 6 by November.
That'd leave us with
No recognised #6 outside of Bissouma (Who leaves for the AFCON and could miss potentially 6 games, I say no recognised because Skipp has yet to actually play there under Ange in 7 games inc pre-season) and midfield options of Bissouma, Sarr, Maddison, Skipp, Bentancur, Lo Celso (2 of which disappear to Africa in January).
We would have to get someone in, in my opinion. I imagine we may go big for Connor Gallaghe
