Fernandinho is also a very good option for that position, he is strong and his distribution is very good, city have the depth to cover for injuries.
City can literally play with 2 CB only. Even if they have trouble covering that position, it won't cost them that much as long as they can dominate the game like usual. Unless they face Liverpool or some team on their same level, City will keep rocking like usual.
Well, it would be interesting to see if they can play with some weakness. At least the title battle would be more interesting than usual if we can see the top 2 slippings once in a while.
Every big club which plays 2 games every week cannot rely only on 2 CB.
They need to make a signing for this position asap. City's CB would be tired and they have problems till the end of the season if they need to play every game until December.
We are talking about two different things.
You are talking about counter attacks and corners while I talk about starting the game with 1 normal CB and the second one to be a DMC as it was stated below by our fellow forum member.
In your case it is normal to have CBs to help the attacking part, but this doesn't eliminate the fact that a team can play with only one CB.
