Ronaldo and his lawyers declined to comment on the warrant to the Journal, which reported that the warrant has been sent to Italy and is making its way through the court system. Police in Las Vegas say they are still investigating a Nevada woman's claim that Cristiano Ronaldo raped her in his Las Vegas hotel penthouse in 2009.
Ronaldo now plays for Juventus which is based in Turin.
Las Vegas police spokesperson Laura Meltzer confirmed than an official request has been submitted to Italian authorities.
Ronaldo, 33, had always maintained that Mayorga's claim is bogus and "plans on cooperating with investigators to prove his innocence", TMZ reports.
Mayorga has alleged that Ronaldo raped her at a Las Vegas hotel in June 2009 after they met at a nightclub, where she was working at as a model to entice guests into the establishment.
According to her lawsuit, Mayorga reported the assault to police later that day and received a medical examination.
She also claims to have voice recordings of Ronaldo making threats as well as sharing offensive thoughts on the LGBT and Jewish communities, among other controversial rants. The case was reopened at the request of Mayorga or someone representing her, Ocampo-Gomez said in October.
Ronaldo has not been served with the lawsuit, Christiansen said.
Nike, which has had a contract with Ronaldo since 2003, said at the time it was "deeply concerned by the disturbing allegations" and would "continue to closely monitor the situation".
Mayorga's lawyers said in September she was now seeking $200,000 in damages and to void the non-disclosure agreement, which they said she was coerced into signing by "personal reputation protection specialists hired" by the soccer star.
Las Vegas police would not confirm the approach.
Lennard went on in a long series of un-threaded tweets, responding to fans and declaring her stance alongside Mayorga.
