33-year-old Ronaldo's lawyer Peter S Christensenen told the BBC "a very natural request" to the BBC.

The Wall Street Journal said the warrant has been sent to the authorities in Italy recently.

Ronaldo denied allegations of rape of Catherine Mayorga in the 2009 Las Vegas hotel.

In relation to asking Ronaldo's DNA samples, his lawyer Christensenen said in the statement, "It is still what Christiano has always said, - what happened in the Vegas Hotel in 2009, it was mutually agreed. So (there) getting his DNA is not a surprise. It is also not surprising that the police requested as part of the investigation. "

German journal Der Spiegel released this news first in October. The magazine said, within a short time after the incident, the police in Las Vegas told the Mayorga.

The police in Las Vegas said they were taking the same steps in relation to the investigation of other rape, about Ronaldo. Italian authorities have been informed about the request of DNA for the Portuguese forward, but they have confirmed it.

The German newspaper reported further that in 2010, there was an agreement reached out to the negotiation with Ronaldo outside of the court. He agreed to not disclose the allegations in exchange for three lakh 75 thousand dollars.

Mayor lawyers are now seeking to cancel the contract for not bringing public to the public.
