More precisely Phil Foden's goal in the 53rd minute, referee Anthony Taylor annulled the goal after watching a replay via VAR, Haaland won the race for the ball from Fabinho by pulling his shirt, so the referee decided to annull the goal, despite being protested by Pep Guardiola, because considered the decision to be controversial.
Haaland did not develop in this match, a tight defense guarded by Virgil van Dijk, Joe Gomez, Andy Robertson and James Milner completely closed Haaland's space, so the striker who has scored 15 goals and three assists was unable to create chances. Kevin De Bruyne and Rodri failed to control the game as usual, so Haaland's well-measured pass wasn't very optimal, even though Haaland had six shots and four on target.
