I’d say Fernandinho trumps the lot. There isn’t another player like him in the squad.
Add Fernandinho to that. Also need to be able to give Stones and Otamendi a break now and again.
Having said that, Napoli away was an intense game in fitness terms and you could see we were blowing due to that. Silva and Walker were everywhere all game due to the midweek rest. We can rotate for final two CL games which will be vital to get us to the new year potentially still in such great form.
I see Gundogan as a potential replacement.
