I refer to balance, as the ability to play on both sides. Walker would struggle to play on the left wouldn't he?
A poster said we couldn't have three Cbs all preferring left side, yet the Liverpool Cbs, (best ever in the world) all right sided. If as a centre back you are not adaptable enough to play on either the left or right of a partnership of two, you shouldn't be at City.
If Koulibaly for example is worth 60, 70 , 80 million, he should be equally comfortable on either side .
If a player is balanced , you rarely notice he is one footed.
Colin Bell for example, couldn't kick it with his left foot, most city fans wouldn't know it though.
