FRANKFURT: The unstoppable Harry Kane set a German Bundesliga record with his hat-trick in champions Bayern Munich’s 4-0 win away to old rivals Borussia in Dortmund.

England’s captain thus became the first player to score 15 goals in his first 10 games in the German championship.

Until now, the record for the best scoring start by a footballer in his debut in the Bundesliga belonged to Klaus Matischak , who scored 13 goals for Schalke in his first 10 games of the 1963-64 championship.

Kane has scored trebles Dortmund, Darmstadt and Bochum, two against Augsburg; and one each against Werder Bremen, Bayer Leverkusen, Leipzig and Mainz.

He tops this season’s scoring charts, one ahead of Stuttgart’s Serhou Guirassy.

Kane scored from close range in the ninth minute after Dayot Upamecano had headed Bayern in front five minutes earlier, both goals created by Leroy Sane.

Stunned Dortmund improved after the break but Bayern’s record signing Kane grabbed his second goal in the 72nd minute, again from close range, to put the game out of reach.

Kane then added the icing on the cake by completing his third hat-trick of the season and second in succession in the league in stoppage time after racing clear and finishing coolly.

“We are so happy that we have him in the team,” captain and goalkeeper Manuel Neuer said, while veteran Thomas Mueller joked that Kane would run out of space for match balls.

“He’s soon going to need another hotel room,” he said.

Victory left champions Bayern on 26 points, two points behind leaders Bayern Leverkusen who had earlier beaten Hoffenheim 3-2 away, helped by a brace from Alex Grimaldo.

Dortmund’s first league defeat of the season ended a run of 25 home matches unbeaten and left them fourth on 21 points.
