Their personalities have rubbed against each other for a while now. It played out behind the dressing-room door, away from the cameras.
Outlook
Repeated incidents may damage dressing-room status.
Given a personal development plan
Asked the manager for a private conversation
Minor
Cause
He has unresolved concerns over his contract. His relationship with the manager is steady but tense. He has already raised this with the manager recently.
The disagreement started because they judged training effort very differently. It played out on the training ground in front of the rest of the squad.
Outlook
Likely to settle unless repeated within the next few weeks.
Dreams of genuine first-team football
Moderate
Cause
He has spent years in the reserves and wants a real chance at first-team level. (His loan record says first-team footballer, his current role says prospect.)
Outlook
Contract request risk increased.
His club is fighting to avoid relegation
Serious
Cause
The points gap to safety, with matches running out, is the issue.
