The striker celebrated his 100th game for the club by playing a pivotal role in the team's victory over Chelsea.
While City were not at their fluid best, they did overpower the home team to secure a 2-0 win.
Post-game, Haaland said: “It’s amazing. I’m really happy. All praise to my teammates, without them it wouldn’t be possible. I’m happy.
“It’s a perfect start. To come here, it’s not an easy game. Coming here is never easy. To keep a clean sheet and win is amazing.
“The players were amazing. It’s not easy to come back and have like two weeks. It was an amazing and impressive team performance.”
