Clijsters is one of the most successful women in tennis history. She played her first WTA match in Antwerp at the age of 15 and was able to win the WTA Tour Finals at the age of 19.
Subsequently, when she was 23 years old, she ended her career because of the family, but returned again and played her last match at the US Open 2012.
In 2009, she managed to win the US Open as the first mother since 1980, and now as a mother of three children she says: "Could I be a loving mom to my 3 kids and the best tennis player I can possibly be?"
Clijsters also spoke about her comeback on WTA Insider Podcast, where she said:
"I don't really feel like I want to prove something, I think for me it's the challenge.
"I have friends who would say, I want to run the New York Marathon before I turn 50. For me, I still love to play tennis. Whenever I'm at a Grand Slam playing the Legends, if somebody asked me hey, do you want to hit some balls, I'm the first one to be like I'll hit. I'll be the hitting partner for your practice today. I still love playing tennis.
"The love for the sport is obviously still there. But the question still is, am I capable of bringing it to a level where I would like it to be at and where I want it to be at before I want to play at a high level of one of the best women's sports in the world.
"I don't feel like I need to prove anything, but I want to challenge myself and I want to be strong again. This is my marathon. This is where I'm saying OK, let's try this."
