Manchester United fullback Luke Shaw faces an injury scan today.

BBC Sport reports Shaw will have a scan on a long-standing groin injury.

Shaw played 85 minutes of Sunday's 3-1 defeat by Watford, after which he was criticised by manager Jose Mourinho.

The Portuguese said the 21-year-old, who returned at the start of the season after breaking his leg last September, was too far away from Nordin Amrabat in the build-up to Watford's second goal.

Shaw has started all five of United's Premier League games so far.
