Manchester United management are unhappy with the poor timekeeping of Mason Greenwood.

The Daily Mail says Greenwood has been spoken to by Manchester United following issues with punctuality.

The teenage striker – who was not in Ole Gunnar Solskjaer's squad for Tuesday's Champions League victory in Paris or Saturday's 4-1 win at Newcastle – is believed to have frustrated officials at Old Trafford with what has been described as 'general tardiness'.

Rumours that an off-the-field matter was behind the decision to keep him at home for the clash in France have been rife.

But Solskjaer delivered a flat 'no' when that was put to him following the 2-1 success over Paris Saint-Germain.
