The Norwegian was kept quiet as City fell to its first defeat of the Premier League season at Liverpool last Monday, but he bounced back in convincing fashion by putting the Seagulls to the sword.

Haaland was the beneficiary of an Ederson assist when he tapped into an empty net for his first, then rifled home a penalty to double up shortly before half-time.

Leandro Trossard dragged Brighton back into contention after the break, but Pep Guardiola's champions weathered the storm before Kevin De Bruyne made the points safe with a trademark long-range strike.

City toiled as Brighton kept things tight in the opening 20 minutes, but the host benefitted from a more direct approach when Haaland latched onto Ederson's lofted ball before shrugging off Aaron Webster to score the opener.

Lewis Dunk denied De Bruyne with a last-ditch block following a give-and-go with Jack Grealish 10 minutes later, but the Brighton defender was at fault when Haaland extended City's lead.

After a lengthy VAR review ruled Dunk had tripped Bernardo Silva in a crowded penalty area, Haaland blasted the spot-kick into the bottom-right corner, giving Robert Sanchez no chance.

However, Brighton needed just eight minutes to half the arrears after the break, as Trossard cut inside from the left before beating Ederson at his near post from 18 yards out, Solly March with the assist.

Trossard then forced Ederson into a reflex save as Brighton continued to push, but their efforts were undone when De Bruyne picked out the top-left corner with 15 minutes remaining, having been teed up by Silva.
