Xavi was quoted telling Spanish radio station Cadena Ser last week:
"Ronaldo is extraordinary but compared to Messi, for me and for everyone who likes football, there are no comparisons.In reaction, Ronaldo who is 2 Ballon d'Ors behind Messi blasted the Al Sadd SC of Qatar midfielder on Saturday.
"Ronaldo is a player of his time. The problem is that there is another who has been pretty much the best player in history."
"The most searched for player on the Internet is me. Those that want to appear on front covers [of newspapers] or promote things speak about me.
"What does it matter to me what Xavi says? He plays where? In Qatar or [somewhere], I don't know. He's won everything but he's never won a Ballon d'Or. I have three.'
"If I were the president of Real Madrid, I would give myself a 10-year contract. Right now I'm not thinking about anything else in my career, all I want is to retire at Real. This is the biggest club in the world and it should have the best players."
