Me and Nadal similar to Messi and Ronaldo: Federer
Swiss tennis star Roger Federer said that his long-standing rivalry with Spanish world number one Rafael Nadal is in some ways similar to that between football stars Lionel Messi and Cristiano Ronaldo. "As similar as we are, Rafa and myself, we're still very different on many levels. I think it's pretty much the same for them[Ronaldo and Messi]," Federer said.
