Manchester United staff have been forced to protect computers from a toilet leak after away fans damaged a bathroom at Old Trafford.
Supporters in the away end of the 74,994-capacity stadium damaged a bathroom earlier in the campaign which led water to leak into offices underneath.
As a result of damage to the facility in the East Stand Upper, workers have had to protect their equipment in case more leaks occur.
Sportsmail understands no further leaks have happened but plastic sheets have been put in place as a precautionary measure during cup games.
