In their fifth game of the Premier League season, Manchester City sought to extend their winning streak.

They quickly took the lead against Nottingham Forest to maintain their streak of opening the scoring in each league game this year.

Erling Haaland scored six goals in the four games City has played thus far against West Ham, Bournemouth, Newcastle, and Crystal Palace, helping City open the season strong with 10 points.

In the 12th, 23rd, and 38th minutes, he added three more to those six.

Watch as Julian Alvarez scores twice in his debut for the Premier League.

Before Julian Alvarez scored his second goal in English football and first in the Premier League on the 65th minute, Joao Cancelo made it four early in the second half.

After receiving a Phil Foden cross and scoring against Steve Cooper's team in just 12 minutes, Haaland added second goal in just 11 minutes with a straightforward finish.

Then, with a header in the six-yard area, he quickly completed his second hat-trick.
