For Bayern, it was a fifth consecutive league win and seventh in all competitions.

Son Heung-Min opened the scoring in the 36th minute, before Stefan Kiessling doubled his side's advantage two minutes after the interval.

Three points behind Bayer in third are Dortmund, who won 3-1 at 10-man Mainz.

Dortmund went in front for a second time with a penalty of their own in the 78th minute, Robert Lewandowski converting after Elkin Soto was dismissed for handball.
Lewandowski then added a second spot-kick in stoppage time to put the result beyond doubt.
The game of the day came at Hoffenheim, who drew 4-4 with Werder Bremen in another fixture featuring three penalties.
Sejad Salihovic twice converted from 12 yards inside 18 minutes for the hosts, but Aaron Hunt and Eljero Elia made it 2-2, with the former also scoring a penalty.
