I still say they'll struggle to fit Silva Sterling and De Bruyne in the same team. Navas isn't great but him keeping the width gives Silva the space to dominate. If De Bruyne gets chucked out right, he won't keep the width and congest the middle. Making it harder for Silva. Kind of the same reason Nasri and Silva didn't really work together.
Silva throughout his time at City has rarely started in a central position, it's only this season and the end of last that he's done so for consecutive matches as far as I recall. Silva and Nasri did work well together, the issue with their partnership is they are similar players who lack pace and directness.
