Cologne - There were thrills, spills, and goals aplenty on the opening day of the 2014/15 Bundesliga season. FC Bayern München and Bayer 04 Leverkusen both got their campaigns off to a winning start, but Ruhr rivals Borussia Dortmund and FC Schalke 04 slumped to Matchday 1 defeats to die Werkself and Hannover 96 respectively.

Matchday 1 will no doubt be remembered for Karim Bellarabi's goal after nine seconds for Bayer 04 Leverkusen against Borussia Dortmund. Apart from scoring the fastest goal in Bundesliga history, the former Eintracht Braunschweig attacker provided a superb assist for Stefan Kießling's second, which sealed the three points for die Werkself in head coach Roger Schmidt's first game in charge of the club. Jürgen Klopp, meanwhile, has plenty to ponder ahead of Matchday 2.

Down at the Allianz Arena, 2013/14 champions FC Bayern München were made to work for their victory over a fearless VfL Wolfsburg outfit. Goals from Thomas Müller (pictured) and Arjen Robben appeared to have put the result beyond doubt, but Ivica Olic's spectacular strike pulled one back for the Wolves, who would have left Munich with a point had Junior Malanda managed to hit the target from point-blank range in the closing stages. However, Bayern held on to start the defence of their title in near-perfect fashion.

Christoph Kramer's 89th-minute goal rescued Borussia Mönchengladbach from the jaws of defeat at home to VfB Stuttgart. Alexandru Maxim had given the Swabians the lead at the Borussia Park, and for a long time it looked as though the Romanian's effort would hand Armin Veh's charges all three points in North-Rhine Westphalia. However, the Foals' very own World Cup winner, who was brought on as a second-half substitute, netted minutes from the end to give Lucien Favre's side a share of the spoils.

FC Schalke 04 surrendered a 1-0 lead at Hannover 96 on Saturday, ultimately going down 2-1 to the Lower Saxony outfit. Klaas-Jan Huntelaar had given the Royal Blues the lead, but goals from Edgar Prib and Joselu earned the Reds a deserved three points. Schalke's cause wasn't helped by the knee injury sustained by defender Sead Kolasinac during the first half, which is set to keep the Bosnia and Herzegovina international sidelined for the rest of the calendar year.

Bundesliga newcomers SC Paderborn were denied a fairytale start to life in the top-flight by a last-minute penalty at the Benteler-Arena. Elias Kachunga and Uwe Hünemeier were on target for last season's Bundesliga 2 runners-up, but the latter's stoppage-time foul on Shinji Okazaki gave Ja-Cheol Koo the chance to rescue a point for Mainz, and the South Korea captain duly obliged. The Bundesliga's other promoted side, 1. FC Köln, were held to a goalless draw at home to Hamburger SV.
