Man Utd's Louis van Gaal interrupted by announcement

Manchester United manager Louis van Gaal's news conference is interrupted by an announcement on the club's public address system.

While discussing United's forthcoming trip to Aston Villa, Van Gaal is halted by a voice calling for a masseur to visit the first-team dressing room.

The Dutchman asks if it is a joke or an emergency, and when told it is not, does not look at all impressed.
