Manchester City beat Manchester United 1-0 at Old Trafford despite playing with 10 men for nearly 70 minutes after Phil Foden's red card in the 23rd minute. Erling Haaland scored the winner midway through the second half following a lengthy VAR review that overturned an initial offside flag. United hit the post twice through Marcus Rashford and Kobbie Mainoo, while Gianluigi Donnarumma made a late save to deny Bryan Mbeumo.

City coach Enzo Maresca secured his first derby win with a tactical masterclass, praising his team's discipline and structure. Referee Michael Oliver and VAR officials Matthew Donohue and Blake Antrobus faced criticism for two key errors: not reviewing Bruno Fernandes' challenge on Foden and incorrectly judging Haaland's goal onside despite Enzo Fernández interfering with play. United failed to capitalize on their numerical advantage, while City's Iliman Ndiaye and Enzo Fernández stood out after halftime adjustments.

Maresca celebrated by charging toward the traveling fans at full-time.
