Manchester United have asked UEFA to change the kick-off time for their Europa League game against Liverpool at Old Trafford on March 17.
The match is currently due to kick-off at 6pm and United are concerned that large numbers of fans will not be able to get to the game at that time.
Trafford Council is also concerned about having thousands of extra fans on the roads and on public transport at rush hour. It is also St Patrick's Day.
UEFA are considering United's request but no decision date has been set yet.
