Manchester United were given a police escort to the airport on Wednesday afternoon over fears of further fan protests directed at the team.
United are due to travel to Rome to face Roma in the second-leg of their Europa League semi-final, but there were suggestions some supporters may attempt to stop the team from boarding their plane.
As a result, a tactical aid unit was deployed to ensure the team’s coach reached the airport without any problems.
It follows angry scenes on Sunday, as United fans broke into Old Trafford and stormed the pitch in protest against the club’s owners – the Glazer family.
