Ronaldo transferred from soccer team Real Madrid to Italian champions Juventus this summer for €100 million (Dh422.1m). Juventus broke their silence on the situation Wednesday afternoon on Twitter, fully backing Ronaldo.
"Cristiano Ronaldo has shown in recent months his great professionalism and dedication, which is appreciated by everyone at Juventus," the team tweeted.
"The events allegedly dating back to almost 10 years ago do not change this opinion, which is shared by anyone who has come into contact with this great champion," Juventus said.
