Ten-man Mainz failed to back up their mid-week shock win at Bundesliga leaders Bayern Munich, but stay on course for a Champions League place, after drawing 0-0 with Darmstadt on Sunday.

Having become the only team to win at Bayern's Allianz Arena stadium on Wednesday by pulling off a stunning 2-1 win in Munich, fifth-placed Mainz were frustrated by Darmstadt, who are just above the relegation places.

Hosts Mainz were reduced to ten men at the Coface Arena when Italian defender Giulio Donati was shown a straight red card on 57 minutes for kicking out at Darmstadt striker Sandro Wagner.

The result leaves Mainz just one point from one of Germany's four Champions League places, with Martin Schmidt's team having one of the best seasons in the club's history.

On Saturday, Bayern stayed five points clear of nearest Bundesliga rivals Borussia Dortmund after a goalless draw between Germany's top two sides.

Despite the lack of goals, the game lived up to its billing as the clash of the teams which have dominated the German league this season at Dortmund's sold-out Signal Iduna Park.

The game's best chance came on 64 minutes when Arturo Vidal's shot for Bayern was palmed onto the bar by Dortmund goalkeeper Roman Buerki.

Bayer Leverkusen came back from 3-0 down to avoid a fourth straight league defeat in a 3-3 draw at Augsburg.

Augsburg's South Korea striker Koo Ja-Cheol scored his first hat-trick in Germany's top flight to put the hosts 3-0 up mid-way through the second-half.

But Leverkusen, who play Villarreal in the last 16, first-leg, of the Europa League on Thursday, fought back as Karim Bellarabi netted, then Augsburg's Paul Verhaegh scored an own goal on 80 minutes.

In the dying stages, Augsburg defender Jeffrey Gouweleeuw's handball allowed Hakan Calhanoglu to convert a 92nd-minute penalty as Gouweleeuw was sent off.

Earlier on Saturday, Wolfsburg warmed up for their Champions League clash at home to Gent on Tuesday with a 2-1 win over Borussia Moenchengladach.

The win moved Wolfsburg up to seventh ahead of the visit of Gent on Tuesday, with the Germans leading 3-2 from the last 16, first leg tie.

Having shocked Leverkusen 4-1 on Wednesday when Claudio Pizarro scored a hat-trick, Werder Bremen pulled further away from the relegation zone with a 4-1 thrashing of bottom side Hanover 96.

The 37-year-old Pizarro claimed his fourth goal in two games, and then provided an assist as Czech international Gebre Selassie added Bremen's third on 56 minutes to leave Werder three points from the relegation spots.

Stuttgart are up to mid-table after their 5-1 thrashing of second-from-bottom Hoffenheim, who stay four points from safety, as defender Georg Niedermeier netted twice.

Schalke are fourth after their 3-1 win at Cologne thanks to goals from Klaas-Jan Huntelaar, Max Meyer and Argentina striker Franco di Santo.
