Munich - Prodigal son Mario Götze was the key figure in FC Bayern München's victory in Der Klassiker, while there's no let-up at closest rivals Bayer 04 Leverkusen.

bundesliga.com rounds up the five biggest stories after another weekend of quality football in Germany's top flight.

All eyes were on Mario Götze (pictured) in his first outing at Borussia Dortmund's Signal Iduna Park as an FC Bayern München player. In the biggest game in Germany and arguably Europe it seems difficult to imagine a more dramatic scenario than the 21-year-old coming on in the second half to break the deadlock only ten minutes later with the cheekiest of toe pokes. Götze never made a secret of his strong ties to his former club, however, and the former BVB fan favourite seemed rather apologetic after his goal.

As much as some might have felt the title-race is all but over after Bayern's win at Dortmund sent them seven points clear of die Schwarz-Gelben, the truth is that the German record champions have another fierce rival hot on their heels with second-placed Bayer Leverkusen trailing the table-toppers by just four points. Stefan Kießling (pictured) and Co. have been remarkably consistent in the current campaign and registered their fourth win from their past five outings in Saturday's 1-0 success at Hertha Berlin.

Their first away win had been a long time coming, but Borussia Mönchengladbach appear to have acquired a taste for success on the road. Following their victory at Hamburger SV on Matchday 11, the Foals registered a 2-0 triumph in this weekend's opener at VfB Stuttgart. With four wins from as many games, fourth place looks to be Gladbach's to lose and, with just three points behind Dortmund, are looking like serious contenders for a place in Europe next season.

Matchday 13 had both good and bad news for Eintracht Frankfurt: Joselu (r.) rediscovering his scoring boots will serve as a welcome boost to the Eagles, the Spanish forward, on loan from 1899 Hoffenheim, having found the net twice on Saturday in the 3-3 draw against FC Schalke 04. Benedikt Höwedes' late equaliser should be a major concern to Armin Veh's charges, however, who have established a habit of conceding in the dying stages this season, seven goals in the last nine minutes of play have already cost Frankfurt ten points.

As much as Bert van Marwijk has given Hamburger SV a new lease of life since taking over the hotseat in late September, his Red Shorts appeared to find it difficult converting good performances into tangible reward in front of their own fans on home soil. Matchday 13 eventually saw the former Netherlands and Dortmund boss register his first win at the Imtech Arena, a 3-1 win against northern rivals Hannover 96 which sees HSV move up to 11th place in the table.
