So we have 4 CMs now - Skipp, PEH, Winks, Bentancur.
Skipp and PEH have been extremely durable. Almost always available and play a lot of minutes. Winks injury record is decent although he hasn't played a ton recently. Bentancur I'm not sure, but it seems he hasn't had a bad injury history.
So that's 2 extremely reliable and 2 fairly reliable CMs when it comes to availability. We aren't going to have room for a 5th CM that is decent. It should be a young guy that could play in a pinch but is still developing (Like Sarr).
I think we could be ok with 4 CMs and then have an emergency option from the youth squad (if there is one).
Obviously, all this could change with unexpected injuries. Having only one forward is way worse than the CM situation.
It limits us tactically though. Conte often goes for 352, that’s 3 CM’s, so he now is forced to go 343 or risk burning his midfield. That’s a major risk, 5 would cover and before today we had more than 5 even if Conte didn’t want to use them.
