Bayern Munich 4-0 Hannover 96

Robert Lewandowski and Arjen Robben both scored twice to help Bayern Munich thrash Hannover and go four points clear at the top of the Bundesliga.

Lewandowski controlled a Rafinha pass to fire the first before Robben pounced on a mistake to double Bayern's lead.

Juan Bernat set up Lewandowski's second and Robben completed the rout with a trademark solo goal.

Meanwhile, Borussia Dortmund's poor start to the league season continued as they lost 1-0 at home to Hamburg.

Lewandowski joined Bayern from Dortmund in pre-season but had only netted twice in his first six league games.

Two crisp finishes will boost the Polish striker's confidence, while at the other end Pep Guardiola's team have now gone seven games without conceding a goal.

It is a different story for Dortmund, as last season's runners-up slumped to their fourth defeat in seven games just three days after their 3-0 victory over Anderlecht in the Champions League.

Pierre-Michel Lasogga scored the winning goal in the 35th minute after an Adrian Ramos mistake as Dortmund dropped to 13th on seven points, 10 behind Bayern after only seven games.

Elsewhere, Hoffenheim went second in the table with a 2-1 victory over Schalke, Bayer Leverkusen salvaged a 2-2 draw against 10-man Paderborn with a 90th-minute Karim Bellarabi equaliser and Werder Bremen drew 1-1 with fellow strugglers Freiburg.
