Manchester United had a slow start to their Premier League game against Watford on Tuesday night, but in the end managed to earn a 4-2 victory at Vicarage Road.

Ashley Young scored twice, while Anthony Martial put the team 3-0 ahead.

The Hornets came close to performing a comeback by scoring twice in the final 13 minutes, but Jesse Lingard's strike wrapped up the win for the Red Devils.

During the second half there was cause for concern from an injury standpoint as Nemanja Matic asked manager Jose Mourinho to substitute him.

The midfielder suffered a muscular problem, but the extent of the injury is not yet known.

The news, though, is bad timing considering that United face Arsenal and Manchester City in the Premier League within the next 12 days.

The club also have a Champions League group game against CSKA Moscow during that period.

As expected, when Matic made way for Ander Herrera, fans expressed concern for the midfielder.
