more width going forward relative to danilo, not cancelo. i agree he can't cross or beat his man, but he takes up positions danilo doesn't, which in itself gives more space to sterling and de bruyne.
i am by no means walker's greatest fan, and i agree his main asset is his pace. but i'm generally against dropping a player after he's just delivered an 8/10 performance. i would also prefer if cancelo was given time to settle and was not rushed into the team. and there's the fact cancelo is a weaker build than walker and so will take time to adjust to the league's physicality.
