I was looking at the BBC Tennis website today, and saw an article saying that they will be doing an interview with Mario soon, one which is comprised entirely of questions sent in by the public, and they are inviting people to send in questions soon that they would like to ask him. It's not a guarantee that all questions submitted will all be selected to be asked in the interview, but there's always a good chance. There is a form on the BBC link below that you can fill in with your name and the question that you want to ask.
The deadline that questions must be sent in by is 1800 hours/6pm GMT on Saturday 15th January.
Ask Mario Ancic
Croatian tennis player Mario Ancic is taking time out from his Australian Open preparations to answer your questions!
He burst on the scene in 2002 beating Roger Federer in the first round of Wimbledon, making him the last player to defeat the two-time champion at the All-England Club.
Ancic grew up idolising his countryman Goran Ivanisevic, and ended Tim Henman's hopes at Wimbledon last year.
He will join Henman and Federer as part of an all-star field at the ABN AMRO World Tennis Tournament in Rotterdam.
What does the Croatian think of his chances this year? And what does he think of his top seed rivals?
Just send us your questions and we will put them to the tennis sensation.
Deadline for all your emails will be at 1800 on Saturday, 15 January.
