Erling Haaland scored five goals to send FA Cup holders Manchester City into the quarter-finals with a 6-2 win at Luton.
The Norwegian hit a 40-minute first-half hat-trick before scoring twice in the second half for his second five-goal performance at City after pulling off the feat against RB Leipzig in the Champions League last season.
Haaland's first four goals at Kenilworth Road were all assisted by Kevin De Bruyne as City's deadly duo were in fine form ahead of Sunday's Premier League derby against Manchester United.
Mateo Kovacic scored City's sixth in a victory which keeps Pep Guardiola's side on course to repeat last season's treble with City a point off Premier League leaders Liverpool, while they are set to reach the Champions League quarter-finals.
Despite City racing into a 3-0 lead, Luton threatened an incredible comeback as Jordan Clark scored twice to make it 3-2, including a stunning first goal from outside the box which was the pick of the eight goals.
But Haaland hit his fourth and fifth goals in the space of three minutes to end their hopes of a memorable turnaround and make it 18 games unbeaten in all competitions for City.
"The players read the game perfectly," said Guardiola. "The connection of Kevin with Erling was great but everyone contributed. Happy to be in the quarter-finals, one game away from Wembley.
"Erling needs a guy with the vision, the quality, the generosity. Kevin is the less selfish player in front of goal. Kevin needs the movement from Erling. We know how aggressive they are.
"Every pass was good. The finishing from Erling was good. We could have scored more, we had two or three more chances, one against one with Krul. But the players read (the game) really well. They did it perfectly.
"My only concern was that Erling had been two months stopped, he couldn't walk, couldn't make anything. When you lose two months, that rhythm is not easy to get back.
"Every game he's getting better. Kevin as well. Step by step, they are coming back."
Luton's focus, meanwhile, will now be on Premier League survival with the gap between themselves and safety increasing to four points after Everton's penalty for breaching financial rules was reduced from 10 points to six after an appeal.
