Jerome Boateng has stressed that Bayern Munich will do everything within their power to hold on to their unbeaten status in Bundesliga, but has acknowledged that they will eventually be beaten.
The reigning German champions have not lost in the league since October 2012, when Bayer Leverkusen proved to be too strong, and Boateng is delighted with his side's superb form in 2013-14.
"It's great that we are on a 51-game unbeaten run in the Bundesliga. Morale is very high within the team and everything is going well," Boateng told Bild.
"But even then, every team can be beaten. We all know that our streak will come to an end at some point.
"We will keep working hard to keep it going as long as possible, though."
Boateng has a contract with Bayern until the summer of 2018 and he has admitted that he could stay at the Champions League holders right until the end of his career, although he refused to rule out a return to his boyhood club Hertha Berlin.
"There's still a few more years to go before my contract runs out. I could very well sign a new deal then. I am feeling very well here at Bayern.
"You never know what will happen in the future, though. A return to Hertha would also be nice..."
The 25-year-old has been a key figure for Bayern this term, making 33 appearances in all competitions.
