Sunderland City Council’s regulatory committee met at 16:00 today and voted to back the proposal put forward by the council’s building control section.
The council’s building control team grants licences which allow events to be held at the Stadium of Light.
So without the council’s backing, the match cannot take place.
On March 26, the same committee set the allocation at 1,700 tickets.
But its members have relaxed their approach after lobbying from United officials, IMUSA, MUST, Reds Away, the Football Supporters Federation and Stretford End Flags.
Today’s decision means United can now proceed with the ticket ballot.
In the run up to the game, Reds Away is working with the Sports Ground Safety Authority, Sunderland FC, Northumbria Police and United to ensure stewards and police do not treat fans unfairly during the game.
