Haaland scored the third in our demolition of the Slovakian side to take him to 11 goals this season and 42 in just 41 appearances in total in the Champions League.
After converting his chance, the Norwegian was swiftly replaced by James McAtee - who added a fourth with his very first senior strike for City.

Asked after the game whether Haaland was disappointed not to have the opportunity to add to his tally on the night, Guardiola took a wider view on things.
“Erling is never disappointed with his manager,” he began.
“As a manager I am more secure and more happy when Erling is on the pitch.
“I will keep him on the pitch all the time but at 0-3 the game was almost over and with this amount of games we have to take care of him.
“He had a big knock last game against Newcastle so that’s why after 0-3 the fantastic goal with the pass from Rico and after that it’s better.”
