Walker wouldn't work in a back three.
Another issue with playing a back three is who plays on the right. Kaboul and Dawson will be in the middle, Vertonghen on the left (and Gallas can play there), but on the right we can play Caulker...but after that, Corluka is slow and King risks being exposed - and that's if either of them are at the club next season. Livermore dropping back?
Exactly, Walker wouldn't work. But surely he can't be dropped! He was one of our best players last year.
