Manchester United's clash with Liverpool on Sunday has been postponed after United fans stormed onto the Old Trafford pitch to protest against the Glazer family.
Supporters were seen carrying flares on the pitch and demanding that the family leave the club following their scheme to join the failed European Super League.
Fans initially blocked gateways and entrances to the ground before breaking into the stadium, with one supporter even seen climbing on the goalposts.
A United statement read: "Following discussion between the Police, The Premier League, Trafford Council and the clubs, our match against Liverpool has been postponed due to safety and security considerations around the protest today.
"Discussions will now take place with the Premier League on a revised date for the fixture.

"Our fans are passionate about Manchester United, and we completely acknowledge the right to free expression and peaceful protest.
"However, we regret the disruption to the team and actions which put other fans, staff, and the police in danger.
"We thank the police for their support and will assist them in any subsequent investigations."
The Premier League also released a statement which read: ""After the security breach at Old Trafford we can confirm the Manchester United v Liverpool match will not kick-off at 16.30 BST.
"The safety of everyone at Old Trafford is paramount.
"At present there is no revised kick-off time. We will update accordingly."
