and they're all players who the manager after Conte wouldn't want
I can understand having one or two DM's in your squad, I think most teams do. But as a coach you need that player you can turn to, to make something happen as a plan B. Whether that be a Modric / Eriksen kind of player that can pick a pass, or a Dembele who can just go past players like they are not there.
I look at the Spurs bench and they are all the same run of the mill midfield destroyers, ok maybe Bentancur has a bit more about him, and tbh I know nothing about Matar Sarr(sp*), but outside that, where is that box to box player? that creative midfield spark? Hojbjerg, Skipp, and Bissouma all seem the same to me, Bentancur just a slightly better version of those guys.
As an incoming coach you would probably keep one of those guys, probably Bentancur, as he seems the best out of the bunch. And ship the rest to whoever will have them.
