Am I the only one not worried about the CM position? Our management work with the players every day, so they have a clear idea about Marchisio's fitness and have seen Bentancur up close.
If they feel Marchisio is going to be fit then that's a massive positive. There's no one on the market who comes close to him, and he'd bench Khedira. I know his injury is worrying, but they know more about whether he's regained fitness than we do.
It also seems they rate Bentancur, and are willing to give him a chance. That would give plenty of cover.
I'm more concerned about RB and CB, but even then not too much. The reason Dani Alves was so important to us was because of our lack of depth at right wing and Cuadrado's loss of form. Now that we're covered there we can get by with a more defensive RB, and give DS and Spinazzola a chance to prove themselves. Not ideal, but Cancelo doesn't seem to be a definitive upgrade, more of a question mark.
At CB I'm more worried about cover in case of injury. As far as it goes Rugani's lack of CL experience doesn't phase me - he's only going to get CL experience by playing and I'd rather he got it now before Caldara arrives otherwise we'll have two young CB's who need to gain CL experience, with even less reliable back up.
