Michael Carrick's first match as Manchester United interim head coach delivered a stunning 2-0 victory over Manchester City. The performance was so complete Pep Guardiola admitted his side might have lost even if Diogo Dalot had been sent off early. Carrick now boasts wins over Guardiola, Unai Emery, and Mikel Arteta.

Carrick reverted to a 4-4-2, trusting Kobbie Mainoo and veteran Casemiro in a midfield partnership his predecessor never used. Harry Maguire returned from injury to help Lisandro Martínez dominate Erling Haaland, limiting City to an xG of 0.45. The tactical shift rewarded players who had been sidelined under the previous system.

The victory ended a long period of fan frustration, with Old Trafford reverberating to positive noise. While Carrick cautioned against overreaction, ex-players like Gary Neville and Wayne Rooney praised the work-rate and United DNA on display. The challenge now is sustaining this standard beyond a single derby performance.
