Why does a footballer need to excel at one particular thing? he can pass, tackle, has lots of energy, get the odd assist and the odd goal.
He hasn’t improved much in two years but he is still young and can still improve in all of the areas listed.
People thought he was going to be ours and England’s next midfielder for years to come just because he was good enough to get games at 17. Sometimes it just doesn’t happen from there, but that is no reason for people to say get rid, he’ll still be a great squad player at this level for years and he can still improve and be more important for the team.
