Manchester United striker Marcus Rashford was furious after being sent off during victory at Burnley on Sunday.

The Daily Mail says Rashford was seen kicking a dressing room door after he headed back down the tunnel following the dismissal.

No damage was caused to the door, but the kick is being seen as a sign of Rashford's "increasing unhappiness" under Jose Mourinho, who it has been claimed used him less frequently than his predecessor Louis van Gaal at Old Trafford.

Although Rashford - who apologised for the incident - has made many appearances under the Portuguese, most of those have come as a substitute.

He averages 54.32 minutes per game under Mourinho, which is much fewer than the 78.5 he played under Van Gaal.
