Phil Foden's early red card for violent conduct left City
facing Manchester United with 10 players from the 23rd minute, but they held
firm until Haaland's 60th-minute finish from Josko Gvardiol's cross sealed a
1-0 win.
VAR overturned an initial offside call, drawing sharp criticism from United's Michael Carrick as 'staggering' and Lisandro Martinez as 'injustice,' with Pro Ref later admitting a VAR error.
Haaland's ninth derby goal extended his record, sparking wild celebrations as City stayed perfect with four wins, while United earned just four points from four games.
