Bayern Munich routed Hannover 4-0 away to increase its Bundesliga lead to 19 points and extend its league record unbeaten run to 47 games on Sunday.

Bastian Schweinsteiger made his first start after recovering from ankle surgery and the Germany midfielder had a hand in both his side's first half goals, as Bayern strolled to its 14th win in succession.

Earlier, 10-man Werder Bremen held on for a 0-0 draw at Eintracht Frankfurt, a result that leaves both sides close to the relegation zone.

Hannover made the better start and Bayern reserve goalkeeper Tom Starke, replacing the rested Manuel Neuer, had to be alert to deny Artjoms Rudnevs in the 15th minute when Szabolcs Huszti played the Latvian striker through.

Bayern gave Hannover a lesson in efficiency and scored with its first attack of note in the 25th when Schweinsteiger spotted Rafinha on the right and the Brazilian crossed for Thomas Mueller to head inside the right post.

Schweinsteiger played a great ball over the Hannover defense for Thiago Alcantara to make it 2-0 with a confident finish nine minutes later.

Hannover threatened briefly after the break when Rudnevs fired over and Starke was called into action to save from Mame Biram Diouf and then block Huszti's effort.

Mueller killed any hopes of a comeback with his second goal in the 59th after Mario Mandzukic laid the ball off with his heel for the Bayern winger to claim his 10th strike of the season.

Mandzukic celebrated his 100th Bundesliga appearance by meeting Rafinha's cross to complete the scoring in the 66th.

Ten-man Werder Bremen held on for a 0-0 draw at Eintracht Frankfurt earlier, a result that leaves both sides perilously close to the relegation zone.

Frankfurt dominated but failed to make the most of its numerical advantage after Felix Kroos was sent off with his second yellow card in the 34th minute.

"We're not at all happy with the point," Frankfurt coach Armin Veh said. "We were the better team even before the sending off."

Joselu should have scored in the ninth but was thwarted in a one-on-one by Bremen goalkeeper Raphael Wolf.

Frankfurt attacking midfielder Alexander Meier grazed the outside of the right post with a free kick in the 29th, shot wide from a promising position in the 78th, and then headed the best chance against the other post with two minutes remaining.

The result left both sides just three points clear of the relegation playoff place.
