The Manchester United Supporters' Trust will take legal action if more away fans aren't allowed to attend the game.
They want the full allocation of supporters to be granted by the council.
The allocation of United has been reduced because of police concerns.
Fans are being treated like second class citizens, according to Must.
It's always a last resort for a Supporters Trust to engage lawyers.
It was confirmed last week that the match will start at 17:30.
The match was moved to the Saturday because of the next day's European match.
The Met Police said that because TV commitments prevented the "high-risk" fixture from starting by 16:45 on the rearranged date, an alternative solution had to be reached.
The safety of fans and those who live and work in the community is the Met's first priority.
There is no history of significant disorder at previous matches between the two sides, according to a letter sent by MUST's legal representatives.
If the council doesn't respond by noon on Friday, 14 October, then they must reserve the right to start judicial review proceedings without further notice.
"United fans and football supporters in general have had their fill of being on the receiving end of unfair and irrational decisions by the council and the police, who seem to consider us to be a public order problem rather than ordinary people enjoying a day out," said a MUST spokesman.
Fans are being treated like second-class citizens despite the fact that tickets had been sold.
The trust stood by the decision and criticized it.
