(CNN)Robert Lewandoski extended his remarkable record of scoring in every Bundesliga match since the start of the season as Bayern Munich thrashed arch-rival Borussia Dortmund 4-0 in 'Der Klassiker' Saturday.
Bayern routs Dortmund in 'Der Klassiker' as Lewandowski extends record
Reigning champion Bayern dominated from the start in its Allianz Arena stadium with Polish international Lewandowski grabbing a double as he was on the scoresheet for the 11th straight league match.
It was a far cry from the sorry 5-1 defeat at Eintracht Frankfurt last Saturday which marked the end of Nico Kovac's spell in charge and left Bayern's title defense on shaky foundations.
The emphatic victory has lifted Bayern up to third in the standings, one point adrift of leader Borussia Moenchengladbach, which can extend the advantage at home to Werder Bremen Sunday.
Dortmund has slipped to fifth, three points adrift after a disappointing afternoon for Lucien Favre's men.
It was the second straight win for interim Bayern coach Hansi Flick, who will stay in charge for the next match against Fortuna Dusseldorf on November 23, the club has confirmed after reports that former Arsenal manager Arsene Wenger had been approached over the vacant job.
Bayern chairman Karl-Heinz Rummenigge told Sport 1: "We will work with Hansi Flick until further notice. I have respect for Arsene. We will call him and clear things up. I don't want to stress him."
Making light of the off-field troubles, Bayern was quickly off the mark in the classic fixture, with Lewandowski powering home a superb header from a Benjamin Pavard cross on 17 minutes.
