Unfortunately, if we play the inverted right back moving into midfield, Stones is the only one of our centre-backs who looks comfortable on the right of the remaining defensive 3 - but playing him on the right means you lose a little of the build-up play he gives you from the central position.The not very good on the ball bit is a bigger problem than the defending IMO. Everything starts at the back and our buildup is no bueno when he's there. Stones is our best and he compensated a bit, but we need the return of Dias-Stones partnership.
