Manchester City's Erling Haaland struck his first two goals at Old Trafford as they dominated Manchester United in a 3-0 thrashing in Sunday's heated Premier League derby.

Pep Guardiola's treble winners are third in the standings on 24 points after 10 games, two points behind leaders Tottenham Hotspur. United, whose defeat was their first in four games in all competitions, are eighth with 15 points.

United had lost six of the past eight matches against their local rivals, including a 2-1 FA Cup final defeat in City's treble campaign last term to match United's 1999 achievement.

"Amazing. A fantastic win and the game was incredible and the team, everything," Haaland said.

"It is definitely one of the best wins," added midfielder Bernardo Silva. "To win 3-0 away with this crowd, I think it is definitely one of the best performances."

Haaland, whose 11 league goals this season equals United's total goal output, converted a penalty in the 26th minute when VAR showed Rasmus Højlund had pulled down Rodri on a free kick.

The Norway striker calmly slotted the spot kick into the bottom-right corner with what was City's first penalty awarded in 27 Premier League trips to Old Trafford.

City, who had lost their previous two league games on the road, dominated shell-shocked United in the second half and their bulldozer of a forward netted again shortly after halftime, when Bernardo Silva made an overlapping run and then dinked a pass to the back post that a rising Haaland headed home.

Phil Foden added the third from close range in the 80th after goalkeeper André Onana pushed away a shot from Rodri that landed at the feet of Haaland for an easy cross to Foden. The goal sent many frustrated United fans to the exits early.

Hojlund had a terrific chance to make amends for his costly foul with a first-half breakaway, but the 20-year-old was jostled off the ball. United midfielder Scott McTominay's shot late in the first half was then punched over the bar by Éderson.

But City had numerous near misses of their own, including a header by Haaland that Onana saved just before the interval.

City crushed Erik ten Hag's visiting United side 6-3 at home last season but lost 2-1 at Old Trafford.
