Haaland's third-minute opener was his 50th goal this term in all competitions – and his 34th in the Premier League, equalling the all-time high first set by Andy Cole for Newcastle in 1993/94, then by Alan Shearer for Blackburn in 1994/95.
But those were both 42-game campaigns – which makes Haaland's prolific exploits all the more incredible.
The Norwegian hitman broke Mo Salah's 38-match season record of 32 goals when he capped off City's 4-1 thrashing of Arsenal in midweek – a result which may well ultimately secure a third successive title for Pep Guardiola's reigning champions.
Only seven of the 22-year-old's 34 Premier League goals have come from the penalty spot – meaning that even without them, he'd still be three clear of Harry Kane in the Golden Boot race.
And with City definitely having nine fixtures remaining in all competitions – 10 if they reach the final of the Champions League – it's not beyond the realms of possibility that Haaland surpasses Dixie Dean's record for the most goals in a single campaign by a player from England's top flight: he's struck 17 times in his last 10 appearances.
Dean scored an astonishing 65 goals in league and cup for Everton way back in 1927/28.
