Bayern Munich snatched their 11th consecutive Bundesliga title in dramatic fashion with a final day 2-1 win at Cologne on Saturday courtesy of Jamal Musiala's 89th-minute goal, grabbing the trophy from the hands of rivals Borussia Dortmund.

Dortmund had gone into the last game of the season in top spot but stumbled to a 2-2 against visitors Mainz 05, allowing Bayern to squeeze past them in the tightest league race in years.

In a climactic season finale, Bayern were celebrating what ended up being an unexpected title win while Dortmund's dreams of their first league trophy since 2012 were left in tatters when they were trailing 2-0 to Mainz early on before battling to a 2-2 draw — but they needed victory to become champions.

Bayern finished on 71 points, ahead on goal difference from Dortmund. RB Leipzig and sensational Union Berlin are third and fourth respectively and will also compete in the Champions League next season.

Hertha Berlin and Schalke 04 were relegated, while VfB Stuttgart will go into the relegation playoff.

With a sea of tens of thousands of yellow and black-clad fans outside the stadium and a sold-out 81,000 crowd inside ready to pop the champagne for their first league crown since 2012, Dortmund went into the game in top spot.

The club had ordered more than 120,000 litres of beer according to club bosses but fans had nothing to celebrate.

Dortmund made it 2-2 deep in stoppage time with Niklas Suele but ran out of time for a winner, with the players left lying on the grass, their heads in their hands and tears in their eyes for the missed title shot.

Kingsley Coman settled Bayern's nerves early on, putting them into the lead with a superbly curled shot into the top corner.

With Dortmund behind from the first half, the Bavarians knew they were now in front and controlled the first half without risking too much.

With Bayern club bosses nervously checking their mobile phones for the score in Dortmund, Cologne earned an 80th-minute penalty.
