Haaland scores four as Dortmund cut Bayern lead

It was the first time the 20-year-old Haaland had scored four goals in a game for Dortmund since his January debut. The Norwegian now has 10 goals in seven Bundesliga matches this season to give him a total of 31 goals in 30 games in all competitions for Dortmund.

After Matheus Cunha gave Hertha a first-half lead at Berlin's Olympic Stadium, Dortmund roared back.

Haaland equalised when he tapped home an Emre Can pass on 47 minutes.

He grabbed his second two minutes later with perfect timing to slip his marker and fire in a Julian Brandt pass.

Haaland wrapped up his hat-trick on 62 minutes, just before Raphael Guerreiro stabbed the ball home from close range to make it 4-1.

Cunha converted a late penalty, but the night belonged to Haaland who finished a move he started with 10 minutes to play.

There was still time for history to be made as Moukoko made a late cameo off the Dortmund bench to replace Haaland. One day after his 16th birthday, Moukoko is the youngest player in Bundesliga history.

Dortmund's romp in Berlin moved them second in the standings, behind defending champions Bayern who stayed top despite a 1-1 home draw with Werder Bremen.

- Bayern held -

Germany goalkeeper Manuel Neuer produced great stops to twice deny US forward Josh Sargent as Bremen earned their first point at Bayern for a decade.

"We had to invest a lot," Neuer told Sky.

The 34-year-old bounced back after conceding six goals in Germany's crushing defeat by Spain in midweek with two brilliant first-half saves in quick succession. He used a boot to block a Sargent shot, then lunged across goal to save from Ludwig Augustinsson. In the dying stages, Neuer then stood tall to block a shot by Sargent, who had broken clear.

Bayern coach Hansi Flick was far from pleased that Bremen took the lead in his 50th game in charge, saying his team "have to defend better".

Bremen deservedly went ahead just before half-time when midfielder Maximilian Eggestein finished off a superb attack.

"We conceded a very cheap goal, that's how Bremen's plan worked and they defended very well," said Bayern forward Thomas Mueller.

Kingsley Coman equalised in the 62nd minute at the Allianz Arena by meeting a Leon Goretzka cross at the far post.

Bayern forward Eric Maxim Choupo-Moting fired over with the goal at his mercy five minutes from time.

However, Neuer's heroics at the other end preserved the draw.
