Phil Foden’s red card midway through the first half – for a reaction to Bruno Fernandes’ kick in his back – made things tough for Enzo Maresca’s Blues in the Italian’s first derby as boss.
However, Haaland’s tight finish on the hour sealed a memorable victory from a brilliant performance behind enemy lines.
Although Manchester United spent more than 67 minutes within the numerical advantage, an outstanding defensive display meant they mustered just three shots on Gianluigi Donnarumma’s goal.
He is set to break record as this is his 9th goal this season making the man of the match yesterday.
