A long-range shot from Robert Andrich took Bundesliga leaders Bayer Leverkusen to a 2-1 home win against Mainz on Friday, setting a new German record of 33 games unbeaten.

Leverkusen were nervy and made a number of uncharacteristic errors, but the victory takes them 11 points clear of Bayern Munich in their bid for a first-ever Bundesliga title.

Bayern, who announced their plan to part ways with coach Thomas Tuchel in the summer on Wednesday, host RB Leipzig on Saturday.
