I'd rather have a fit Lewis in there Boz. Walker has the class, but he didn't have the energy to run into a space to receive a ball, or to deter opponents running past him.Don’t think Walker has played much pre-season so seemed a bit of a gamble to start with him, though a better defensive mid option than Lewis. Sounds like we’re still deficient in the creating, so just switching forwards won’t cut the mustard.
