Callum Robinson

Might be waiting a long time. Apparently he's got growing pains, bless him.
I don't recall Rooney at 16 or Giggs at 17 needing years because of growing pains, and neither were fully developed at that age physically.
As Fergie used to say, if they're good enough, they're old enough.

Wtf is going on these days?
A kid is a kid at 15, not in his 20's ffs.

Were either of them six foot four?

And Giggs had loads of injury problems throughout his career
