Bundesliga clubs and players have lavished congratulations on Angelique Kerber, who beat Serena Williams in Sunday's Australian Open final to become the first German to win a tennis Grand Slam since Steffi Graf in 1999.
Kerber has long been a huge football fan. In an interview with bundesliga.de in 2013 she admitted she had been "a Bayern fan right form being a small child, despite coming from northern Germany. Everyone around us supported HSV or Bremen, so I was the odd one out."
That passion still exists as Kerber revealed that "the tennis team I talk about football all the time, especially with Julia Görges and Andrea Petkovic."
If they weren't already, everyone in the Bundesliga is now a confirmed fan of the tennis star as well following her historic triumph, not least her favourite club...
"FC Bayern congratulates you on your amazing triumph. Have a blast!"
And the other clubs in the league were just as delighted...
VfB Stuttgart tweeted "greaaaaaat tennis! Congratulations on your triumph! Amazing! White-and-red greetings from Stuttgart"
Players were quick to offer their congratulations as well.
