The hosts did not have it easy against a determined Leverkusen side, who drew level before the defender stepped up to give his team a priceless three points
Mats Hummels netted his first Bundesliga goal for Bayern Munich as Carlo Ancelotti's side battled to a 2-1 victory over Bayer Leverkusen on Saturday.
The Germany international returned to the club from fierce rivals Borussia Dortmund in the close-season and made a decisive intervention at the Allianz Arena to end a poor run of form for his team.
Ancelotti kept faith with just four of the starting XI from the shock 3-2 defeat at Rostov in the Champions League in midweek, and the fresh faces - including Hummels - managed to help end their three-match winless run in all competitions.
