Serena Williams says she agrees with Roger Federer and Andy Murray, who have both advocated for more blood testing in tennis.

“Sure, why not? I don’t have a problem with it,” Williams told reporters in Dubai. “I get drug tested a lot, all the time, I don’t know about anyone else on the tour, maybe they put all their money into drug testing me. I don’t understand, maybe they should branch out a little bit. They’re always at my house, doesn’t matter if I’m in Paris they’re there. I literally was in Mauritius and they were there, and Mauritius is really far I can tell you. I guess they spend all the money buying tickets to come to where I travel!”
