Bayern Munich thrashed Borussia Dortmund 5-0 to take over top spot in the Bundesliga on a landmark night for Robert Lewandowski. The 100th league instalment of Der Klassiker was a one-sided affair as Mats Hummels, Lewandowski, Javi Martínez and Serge Gnabry had Bayern in dreamland before the break.

Lewandowski put further gloss on the rout with Bayern’s fifth in the final minute and the German champions are now in pole position to retain the title. Bayern were nine points adrift of Dortmund in December but the Bavarians are now one point clear of their rivals with six games remaining.

Lewandowski’s first strike meant he become the fifth player in Bundesliga history to score 200 goals – only the former Bayern favourite Gerd Müller has reached the total quicker. Dortmund had the perfect chance to shock Bayern within six minutes when Jacob Bruun Larsen and Marco Reus combined to set up Mahmoud Dahoud from 16 yards.

Dahoud was unmarked and had the goal at his mercy, but he could only strike the outside of a post with the returning Manuel Neuer beaten in the Bayern goal. It was to prove a costly miss – Bayern were ahead four minutes later as the former Dortmund defender Hummels headed home Thiago Alcântara’s corner.

Lewandowski, another former Dortmund player, doubled Bayern’s lead seven minutes later when he robbed the dawdling Dan-Axel Zagadou 30 yards out. The Pole ran on to the loose ball and chipped it over the advancing goalkeeper Roman Bürki to volley into the empty net.

It was a wonderful piece of opportunism and took Lewandowski level with Müller on 14 goals as the highest scorer in this fixture. Lewandowski was denied the outright record instantly as Bürki prevented further embarrassment for Dortmund.

The Swiss goalkeeper tipped a Thomas Müller header on to the crossbar and then denied Hummels and Lewandowski as Bayern threatened to score from every attack. But Bayern’s third goal did arrive after 41 minutes, Martínez sweeping home from the edge of the area after Bürki had parried Müller’s close-range volley and Dortmund had failed to clear the danger.

The visitors were in disarray again two minutes later as Gnabry met Thomas Müller’s cross to score with a powerful downward header. The second half lacked the intensity of the first period with both sides seeming to conserve energy for the crucial games to come.

Gnabry fired wide as Bayern found late impetus and Lewandowski sent a shot over the crossbar at full stretch from six yards. The Polish striker picked up a booking after being involved in a couple of heated incidents with Dortmund defenders, who seemed keen to rattle him.

However Lewandowski had the final word after he was denied by a brave block from the substitute Julian Weigl. Gnabry broke down the right for the umpteenth time and teed up Lewandowski, who had the simple task of finishing from a few yards out to become the highest scorer in Der Klassiker history.

“We put them instantly under pressure. We wanted to attack them early and we overran them,” Bayern’s coach, Niko Kovac, said. “It was exactly what we had set out to do. We may have had some slip-ups this season but that happens. There were many critics of this team and that is why I am really happy for my players today.”

“This was clearly a lesson for us today,” said the Dortmund coach, Lucien Favre. “We have to accept it. They were faster, more aggressive, more skilled. We now must focus on the next game.”
