Walker's been a fantastic player at City, but he's starting to look 34 and without being too critical, I would suggest that he's probably appeared at one tournament too many.
It would be great if he accepted a lesser role, as Rico seamlessly acquired more minutes in a successful team, but history tells us that it won't be that smooth.
Slightly different with Bobb as he looks a genuine quality prospect. He just needs more games, either as a late substitute in the PL or as a starter in the cup competitions
