Forlan said on Twitter that he had never said anything about Ronaldo.
According to the Mirror, he stated that "Ronaldo was an egotist in the dressing room, not like Beckham,"
"Cristiano always wanted to be near a mirror. He spent all day looking in the mirror."
But now, the 40-year-old Uraguarian claims on his official twitter that, "Unfortunately, I am forced to clarify that I never said what some media mentioned about Cristiano Ronaldo.
"I have absolute respect for all the teammates and rivals with whom I have been lucky enough to play."
Forlan, who announced his retirement from football earlier this month over a year after he left his final club Kitchee in the Hong Kong Premier League.
