So as it stands, we'll have Grujic, Henderson, Allen, Milner, Can, Stewart and Lucas competing for the CM spots next season. And that's without the potential addition/s of Zielinski/Dahoud, or another.
When you consider that we typically only play with two CMs then surely something has to give? I reckon we could be in for a few surprises this summer.
Personally, I'd move Lucas and through gritted teeth, one of Allen and Henderson on.
