Bayern Munich 2-1 Bayer Leverkusen

Mats Hummels scored 19 Bundesliga goals for Borussia Dortmund before his summer move to Bayern

Mats Hummels scored his first Bundesliga goal for Bayern Munich as they beat Bayer Leverkusen to move to within three points of shock German league leaders RB Leipzig.

Thiago headed the champions ahead after Bernd Leno parried Philipp Lahm's shot.

Hakan Calhanoglu scored a brilliant leveller for the visitors, smashing the ball over Manuel Neuer at his near post after a one-two with Julian Brandt.

But Hummels headed in Joshua Kimmich's corner to win it for the hosts.

Bayern, who are chasing a fifth consecutive league title, had lost their previous two games in all competitions, and failed to win in three, in a relatively slow start under manager Carlo Ancelotti.

Elsewhere, Borussia Dortmund dropped down to sixth after a 2-1 defeat at Eintracht Frankfurt, with Haris Seferovic scoring the winner moments after Pierre-Emerick Aubameyang's equaliser.

Fifth-placed Hoffenheim drew 1-1 at Borussia Monchengladbach to remain unbeaten - although they have only won five of their 12 games.

Former Arsenal midfielder Serge Gnabry continued his good season with the equaliser as Werder Bremen drew 2-2 at relegation rivals Hamburg.
