It took Erling Haaland just 19 minutes and 41 seconds to score his first UEFA Champions League goal for Manchester City.
Haaland stretched to volley home a Kevin De Bruyne cross from close range to give City an early lead over Sevilla in Spain on Tuesday night.
This was Haaland's 24th Champions League goal in his 20th appearance at this level.
He had scored eight in six appearances for Salzburg and 15 in 13 for Dortmund.
But Haaland was not done.
After Phil Foden had doubled City's lead 13 minutes into the second half with a fine solo goal, Haaland took his career UCL tally to 25.
Foden's low shot was spilled by keeper Bono and Haaland gobbled up the rebound.
Ruben Dias made it 4-0 to City in added time.
Haaland's double saw him break a Champions League record by becoming the youngest player to score 25 goals in the competition.
