LUTON, England - Erling Haaland roared back to his best form with a five-goal salvo as Manchester City thumped Luton Town 6-2 at Kenilworth Road to reach the quarterfinals of the FA Cup on Tuesday.

Luton had no answer to the marauding Norwegian who bagged his eighth City hat-trick before halftime and then scored twice more after the break to kill off a stirring Luton revival.

The 23-year-old Haaland's first four goals were all created by Kevin De Bruyne. Mateo Kovacic also got on the scoresheet for holders City who are unbeaten in 18 games in all competitions.

Luton did threaten an unlikely comeback when Jordan Clark found the top corner with a sublime effort on the stroke of halftime and netted again early in the second half to make it 3-2. But a strong City side instantly found another gear to cruise into the hat for the last eight.
