Manager Ole Gunnar Solskjaer says Manchester United will fight to delay Manchester City's Premier League title celebrations "as long as we can".
But Solskjaer's side fought back to win 3-1 at Villa Park.
"At least we don't travel back to a party on the blue side tonight," the United boss told BBC Sport.
Solskjaer, whose side are 10 points behind Manchester City with a game in hand, admitted United would have to pull off "the biggest upset in football history" to win a first Premier League title since 2013.
However, he added his players would take satisfaction from postponing City's title confirmation further.
