Haaland managed to score Manchester City's first and second goals before being substituted at halftime by Pep Guardiola. 

 It's own goal (caused by Haaland) shortly before halftime put them up 3-0.

Riyad Mahrez scored from the penalty spot for the fourth goal, and Julian Alvarez scored his first UCL goal to round out the scoring.

Man City has won three from 3 matches in the UEFA Champion League group stage. 

They maintain a three-point advantage over second-placed Borussia Dortmund, who also won on Wednesday. 

On Wednesday, Copenhagen repeatedly tried only two shots in 90 minutes, the initial of which came in the 72nd moment, after Man City had already repeatedly tried 24.

Whereas Man city's Haaland took four himself, in just 45 minutes, as the midfield playmakers 

Manchester City now looks to exploit the space behind the defense whenever it presents itself, rather than aimlessly loitering around the penalty area. 

Chelsea hopes alive with a dominant 3-0 win over AC Milan
