Munich, Germany (SportsNetwork.com) - Bayern Munich moved four points clear at the top of the Bundesliga on Saturday as two goals apiece from Robert Lewandowski and Arjen Robben helped the club roll to a 4-0 win over Hannover at the Allianz Arena.

Bayern seized control of the match early on and was never in any real danger of dropping points after both Lewandowski and Robben scored in the opening 13 minutes.

Lewandowski scored again before halftime to put Bayern up 3-0, and Robben tallied his second goal of the contest 11 minutes from time to wrap up the comprehensive victory for Pep Guardiola's side, which has won five of its seven games in league play.

It took the home side just six minutes to go in front as Rafinha lifted a ball over the top of the defense that allowed Lewandowski to bring it down and slot a shot past goalkeeper Ron-Robert Zieler.

Hannover defender Felipe handed Bayern a second goal in the 13th when his failed clearance allowed the Dutchman to score from the top of the box.

Bayern went on cruise control for much of the rest of the game, but still managed to add two more goals, with Lewandowski once again getting in behind the defense to score his second goal of the match six minutes before halftime.

Robben wasted a good chance in the 70th to add to his total, but he beat Zieler nine minutes later with a powerful effort to give him three league goals on the season.

Borussia Dortmund's season got even worse on Saturday as the club dropped a 1-0 decision at home against last-place Hamburg, which entered the match without a victory.

Pierre-Michel Lasogga struck the lone goal for Hamburg in the 35th minute, leaving Dortmund 10 points back of Bayern after just seven games.

Bayer Leverkusen needed a late goal from Karim Bellarabi to salvage a 2-2 home draw against Paderborn after the visitors went up 2-1 in the 87th through Moritz Stoppelkamp.

Hoffenheim climbed into second place after downing Schalke, 2-1, with goals from Tarik Elyounoussi and Adam Szalai in the opening 30 minutes, Werder Bremen and Freiburg are both still searching for their first win of the season after the two sides played to a 1-1 draw, and Eintracht edged Cologne, 3-2, thanks to an own goal from Kevin Wimmer 11 minutes from time.
