On Saturday, Bayern Munich defeated Mainz 3-1, thanks to a goal from Harry Kane, his ninth goal in eight league games. Bayer Leverkusen had earlier triumphed at Wolfsburg to take the top spot.
After Kingsley Coman had given Bayern an early lead, Kane continued his incredible run since leaving Tottenham in the summer, heading in from close range.
Just before the break, Anthony Caci gave Mainz, who had defeated the defending German champions three times in their previous home league games, a little reprieve.
Stefan Bell, a defender for Mainz, missed a counterattack that would have tied the score early in the second half despite being just centimeters away from home.
