Manchester United have had burnout fears for Mason Greenwood.

The teenage starlet finished the campaign in great form for the Red Devils - netting eight goals during a clinical spell that began in March - and he looked nailed on to earn a place in Gareth Southgate's England squad.

But Greenwood was forced to withdraw from the group preparing for Euro 2020 as he bids to recover from an underlying injury - believed to be relating to his groin - before next season kicks off.

The Athletic reports Greenwood's fitness issues were evident towards the end of the campaign having told coaches about his struggles after he was substituted by Ole Gunnar Solskjaer in the 1-1 draw against Fulham.

Greenwood complained of feeling "utterly exhausted" last month after being hauled off.
