Robert Lewandowski netted twice as Bayern Munich returned to the top of the Bundesliga on Saturday with a 5-0 win over Wolfsburg after RB Leipzig lost their unbeaten record.
Leipzig's shock 1-0 defeat at bottom side Ingolstadt, who finished with ten men, ended their three-week stint as leaders as Carlo Ancelotti's Bayern cut the three-point gap and regained top spot on goal difference with both teams on 33 points.
Second-placed RB had their 13-match unbeaten run ended -- a record for a club at the start of their first Bundesliga season -- as coach Ralph Hasenhuettl endured a horror return to Ingolstadt, who he left after last season.
Ingolstadt's Australia striker Mathew Leckie was sent off for two yellow cards in quick succession in the tense final stages.
But his team held on for the win which took them off the bottom leaving Darmstadt, who lost 1-0 at Freiburg, now last.
