Bastian Schweinsteiger has apologised after a video of him singing a derogatory song about Borussia Dortmund was posted on the internet.
The Germany and Bayern Munich midfielder was captured leading a chant of 'BVB, sons of bitches' at a party.
The 29-year-old said on his official Facebook page: "Hello, I'm sending you all a message from my holidays, as it's come to my attention that a video of me has found its way onto the internet.
"I'd like to say sorry to all fans, players and officials at Borussia Dortmund. I won't try to play this down, it's obviously a well known fan song, but I didn't want to insult anyone with the offensive word.
"It's important for me to articulate that now. I get on with all Dortmund players really well, especially Kevin Grosskreutz. It was an unhappy situation, so sorry again to all Dortmunders, I hope the fans will understand it. All the best, I hope everything's ok again. Your Basti."
Schweinsteiger was part of Germany's World Cup-winning squad in Brazil earlier this summer.
