A review of the weekend's action in the German Bundesliga, including Bayern Munich's victory over Bayer Leverkusen.
Bayern Munich completed half a century of Bundesliga games without defeat on Saturday with victory over the only remaining league side they have not beaten yet this season, Bayer Leverkusen.
Bundesliga top-scorer Mario Mandzukic headed them in front just before the break with Bastian Schweinsteiger sealing victory shortly after the interval.
Stefan Kiessling nodded in a consolation in stoppage time to make the final score 2-1.
With Borussia Dortmund losing earlier on Saturday, Bayern now have a 23-point advantage at the top of the table and could wrap up the title quicker than anybody ever before with a win at Mainz next weekend.
Borussia Monchengladbach picked up their first win of 2014 as they completed a league double over Dortmund with a 2-1 win at the Westfalenstadion.
The visitors weathered a storm before Raffael put them in front and Max Kruse added a second for Lucien Favre's men before the interval.
Havard Nordtveit was sent off midway through the second half and Milos Jojic reduced the arrears with 13 minutes to go, but Dortmund were unable to find an equaliser as they lost to Gladbach for the second time this season.
On Sunday, Freiburg were the big winners on an important day in the relegation dogfight as they thrashed Eintracht Frankfurt 4-1.
Freiburg remain inside the bottom three but, with Hamburg beating Nurnberg 2-1 in their own lowly battle, Christian Streich's side are now just a point from safety.
Both Hamburg and Nurnberg are the teams directly above them, on 23 points, with Frankfurt now dangerously lingering only four points ahead.
Julian Schuster (34) and Karim Guede (54) gave Freiburg a 2-1 advantage and while Joselu (59) quickly pulled one back it was the only moment of joy for Eintracht.
Felix Klaus (70) restored Freiburg's two-goal cushion before Guede grabbed his second in injury-time.
Hamburg struck twice in the last 10 minutes to win at home to Nurnberg.
Hakan Calhanoglu belatedly gave Hamburg the lead in the 80th minute and Mike Frantz's own goal doubled their advantage before Josip Drmic managed to score Nurnberg's consolation goal on the stroke of full-time.
On Saturday, Mainz recovered from two goals down to win 4-2 at Hoffenheim and boost their chances of playing in Europe next season.
Eugen Polanski and Roberto Firmino gave Hoffenheim the lead after the first half ended goalless.
Three goals in eight minutes then saw Mainz turn the game around with Eric Maxim Choupo-Moting, Benjamin Saller and Shinji Okazaki all on target. Okazaki struck again in stoppage time to seal Mainz's win and take them up to fifth in the table
Elsewhere, Hannover celebrated victory on the road for only the second time this season as they recorded a 3-0 victory at Hertha Berlin to ease their relegation worries.
Lars Stindl, Jan Schlaudraff and Szabolcs Huszti were all on target in the second half for Tayfun Korkut's men.
Bottom-placed Eintracht Braunschweig earned a valuable point in their fight against relegation from the Bundesliga by holding Wolfsburg to a 1-1 draw.
Luiz Gustavo put the Wolves ahead after 36 minutes, but Karim Bellarabi salvaged a point for the hosts three minutes after the interval.
In the other game, Werder Bremen and Stuttgart split the spoils in a 1-1 Bundesliga draw at the Weserstadion.
Georg Niedermeier gave Stuttgart the lead after 55 minutes before Aaron Hunt scored the equaliser for the home side in the 79th minute.
On Friday night, a Klaas Jan Huntelaar brace earned an efficient Schalke all three points in a 2-1 victory over luckless Augsburg in Bavaria.
Tobias Werner gave Augsburg the lead in the fifth minute of a game they dominated from start to finish, but two chances were all Schalke and Huntelaar needed to turn things around and take the Royal Blues up to third.
Augsburg will wonder how they had not managed to continue their own push for a place in Europe after creating enough chances to win several matches, only to come away empty-handed.
