Cristiano Ronaldo is ready to play for Juventus against Udinese this weekend despite the rape claims made against him, coach Massimiliano Allegri said yesterday as the Italian champions try to maintain their perfect start to the Serie A season.

"Ronaldo is doing well, he is ready to play. His professionalism and his composure on and off the pitch are not in question," Allegri said. "He is ready to return to action." US police said on Monday they had re-opened an investigation into accusations by former American model Kathryn Mayorga that the Portuguese player raped her in a Las Vegas hotel in June 2009.
