Harry Kane scored a hat-trick as Bayern Munich took just 13 seconds to open the scoring against newly promoted Holstein Kiel, returning to the top of the Bundesliga with an emphatic win.
Kane nodded on for Jamal Musiala to run clear and score Bayern's joint second-fastest goal in the Bundesliga era.
Kane scored twice in a rampant first half either side of an own goal from Nicolai Remberg, with former Crystal Palace forward Michael Olise grabbing his first Bayern goal after the break.
Kane then scored a penalty in stoppage time to wrap up victory and a fifth hat-trick for the club.
Vincent Kompany's side have won all three league games while Kiel - in their first Bundesliga season - have yet to record a point.
Only striker Giovane Elber has scored a faster goal in the Bundesliga for Bayern than Musiala, the Brazilian netting after 11 seconds against Hamburg in 1998.
Musiala made no mistake after two defenders collided before former Tottenham and Fulham man Lewis Holtby gave the ball away and Musiala teed up Kane for the second.
Kane has now scored against all 18 teams he has faced in the Bundesliga, and after Remberg turned into his own goal the England captain curled in a fine second from 20 yards.
Olise swept in a rebound after Alphonso Davies had a shot saved to put Bayern 5-0 up, but Armin Gigovic gave the home fans something to cheer when he headed in a late consolation, their first goal at home in the league.
There was still time for Kane to win - and convert - a spot-kick in added time.
