Bayern Munich continued their incredible form as Franck Ribery scored two in a 7-0 rout of Werder Bremen.
The German champions are now 40 games unbeaten and eased to a 3-0 lead at half-time before finishing the job with four more in the second.
Assani Lukimya gave Bayern a hand by scoring an own goal in the 21st minute, but Ballon d'Or candidate Ribery soon took charge of the match to inspire Bayern to a convincing victory.
Daniel van Buyten made it two in the 27th minute before the Frenchman got his name on the scoresheet to give Bayern their biggest half-time advantage of the season so far. He then teed up Mario Mandzukic to make it four before Thomas Muller put Bayern 5-0 ahead.
Ribery added a sixth before Mario Gotze completed the rout to both compound Bremen's misery and help assert Bayern's authority on the Bundesliga once again.
Bayer Leverkusen reduced the arrears on Bayern Munich to four points again with a 1-0 win at Borussia Dortmund which leaves the Westphalians now 10 points adrift of the Bundesliga leaders.

Jefferson Farfan put Schalke in front from the penalty spot, but Raffael levelled with a fine long-distance effort before Max Kruse snatched victory with a spot-kick of his own.
Schalke played the second half with only 10 men after Benedikt Howedes was shown a red card, and they failed to find an equaliser as the pressure mounts on coach Jens Keller, whose side now have a decisive Champions League fixture with Basle to come.
Stuttgart returned to winning ways in style with a 4-2 win over Hannover which took them above their opponents and up to 10th place.
