Tin foil hat time...
I think next season we’re going to see a transition in Walkers game, with him slowly moving inside to RCB (in a back 3) and CB (in a back 4). He’ll still play a lot at right back but I think his lack of technical ability on the ball and his slow thought process in possession is getting exposed more and more in our system.
Losing Kompany (and potentially Otamendi) will leave us short in central defence and I only expect us to sign one, with a new technically gifted attacking right back also coming in to allow us to play a back three, especially if we can get Mendy fit.
Walkers pace, strength and recovery ability is perfect for defending counter attacks centrally. He’s got the height and aggression to fight battles against physical strikers and I really think it’ll protect and prolong his career moving inside so it just seems a logical move.
