In the highest-scoring Manchester derby in history, the City striker's most recent treble establishes a competition record.
Erling Haaland broke a number of records as Manchester City easily defeated Manchester United 6-3 on Sunday, becoming the first player to score three straight home hat-tricks in Premier League games.
City's win was the highest-scoring Manchester derby ever, in the 187th competitive meeting between the teams.
Haaland had already written his name into the history books before kick-off, with his competition-high nine goals in his first five Premier League appearances.
And he followed his home hat-tricks against Crystal Palace and Nottingham Forest with an historic treble against Erik ten Hag's team.
Haaland was also the first City player to score a hat-trick in the derby in the Premier League, and the first in the top flight since Francis Lee in December 1970.
His feats are underlined by the fact that he eviscerated Michael Owen's mark of being the fastest player to score three Premier League hat-tricks. While Owen needed 48 matches to get a hat-trick of hat-tricks, Haaland required only eight.
