Pep Guardiola's men began our defence of the Premier League in confident fashion, dominating possession in the capital.
The slick passing paid off with just under ten minutes until the interval as Ilkay Gundogan slipped through Haaland, who was brought down by Alphonse Areola inside the box.
The 22-year-old picked up the ball and coolly finished into the bottom corner from the penalty spot to claim his first goal for City.
Five minutes after the hour mark, Haaland found the net again, latching onto Kevin de Bruyne's pass before slotting in expertly.

Just minutes later, the Norwegian almost had a hat-trick, but his header from Jack Grealish's cross sailed over the bar.
City remained professional to secure the three points, kicking off our defence of the title in perfect fashion!
