I have been very busy preparing and practicing for the US Open Tennis Championships but took a break to answer the #ALSIceBucketChallenge made by my friends Johnny Mac, Niall Horan and Sabine Lisicki. I’m proud to donate and be part of this great movement to defeat the disease. Now I challenge Conchita Wurst, Mr. Bean and Michael Jordan!

U pauzi priprema za #USopen odgovorio sam na izazov nekih sjajnih ljudi. Baš mi je drago da sam deo #ALSIceBucketChallenge pokreta! I sad izazivam Conchitu, Mr. Bina i Džordana :)

Thank you for all of the bday wishes !! ❤️🙏🏼🫶🏼 https://t.co/aZrrZlFhMY
