23-time Grand Slam champions Serena Williams' husband Alexis Ohanian hit back at Romanian billionaire and Madrid Open owner Ion Tiriac, for making racist and sexist remarks on his wife. In an interview with a Romanian television channel, Tiriac said that at this age and the weight she is now, Serena does not move as easily as she did 15 years ago. He added that if the 39-year-old tennis star had a little decency, she should retire. The remarks didn't go down well with Ohanian who tweeted to say that no one gives a damn what Ion Țiriac thinks. In another tweet he called Țiriac a racist and a sexist clown.
