Pep Guardiola conceded Manchester City may not be getting the best out of Erling Haaland after the Norwegian failed to find the scoresheet again.
Haaland has already broken a slew of records with his extraordinary performances, becoming the first player to score 20 Premier League goals before the turn of the year - even with a break for the World Cup. The forward has not been used as much recently with Guardiola mostly resting the player for cup competitions, but his goalscoring has slowed.
City's No.9 failed to find the net at Chelsea at Stamford Bridge last week, was unable to change the game at Southampton, and went goalless again in the Manchester derby. Jack Grealish's goal looked set to have given the Blues the victory before a sucker-punch from United after a hugely controversial refereeing decision.
