Defending champions Borussia Dortmund went top of the Bundesliga for the first time this season after defeating neighbours Schalke 2-0 as Bayern Munich, who meet Mainz tomorrow, dropped to third in the table.
Only one point separates the top three teams with Dortmund and Borussia Moenchengladbach on 29 points, however, Bayern can regain top spot should they win at Mainz.
Having had their UEFA Champions League hopes all but ended with defeat at Arsenal in midweek, Dortmund picked up their seventh win in eight league games with goals from Polish striker Robert Lewandowski and Brazilian defender Felipe Santana.
Lewandowski scored his ninth league goal when he headed home on 16 minutes and Dortmund made sure of their first home win over Schalke since 2007 when Santana fired home from 13 metres out in the Ruhr Valley derby.
After losing German midfielder Sven Bender to a broken jaw at Arsenal, and only having had teenage star Mario Gotze confirmed in the starting line-up on Friday night after a knee injury, Dortmund coach Jurgen Klopp praised his team.
"We didn't let the opponents back into the game, we were stronger in the middle of the pitch," said Klopp. "It was just a good game of football from the first until the last minute and we deserved to win."
Leverkusen, Hertha share six goals
Having booked their place in the knockout phase of the Champions League with a late win at home over Chelsea on Wednesday, Bayer Leverkusen sealed a 3-3 draw at Hertha Berlin.
Swiss striker Eren Derdiyok, who scored the equaliser against Chelsea, hit a hat-trick, but having put his side in the lead in the 79th minute to make it 3-2, Berlin's teenage striker Pierre-Michel Lasogga levelled eight minutes from time. The draw leaves Leverkusen sixth in the table, while Berlin are tenth.
Hamburg's new coach Thorsten Fink has now gone five games unbeaten after his side drew 1-1 at Hannover, leaving his side 14th, while Hannover are now eighth.
Bottom side Augsburg picked up only their second victory of the season, and their first home win, when they inflicted a 2-0 defeat on 2009 champions Wolfsburg. Midfielder Daniel Brinkmann scored his first goal of the season when he fired home on 65 minutes from a tight angle before Albanian striker Edmond Kapllani scored their second in the fourth minute of injury time.
Augsburg's win tightens things at the foot of the table with two points now separating the bottom five sides. Midtable Nurnberg enjoyed a 1-0 win over Kaiserslautern, while Hoffenheim grabbed a 1-1 draw with Freiburg.
On Friday, Gladbach knocked Bayern from top spot in the league with a 3-0 win at Cologne with former Germany striker Mike Hanke getting off the mark for the season with a double to seal his team's fourth straight win. Having kept his side up last season only after they won a relegation play-off, Swiss coach Lucien Favre has worked a miracle this term by turning Gladbach into genuine title contenders.
