I do think Walker will go this summer to Saudi, seems a lot of links and him even talking publicly. If we finished the season on a high again it would be a perfect ending for him.
If we were to sign Branthwaite I think Akanji gets minutes at RB/Wide RCB like last season. Also we have Rico.
I think the only way we sign a new RB is if Walker goes. Frimpong seems a natural replacement as does Couto as both are more wingbacks. Then there is talk of Kimmich who could play both RB and CDM. Reece James? I think we consider it if he's available but would we be confident on his long term fitness, who knows.
