Cassano has been critical of the released Manchester United striker during the Euros.
He said, "Portugal on Monday did not deserve to win because Uruguay had 4-5 sensational chances.
"He also wanted the goal the other night despite the ball having passed a quarter of an hour earlier. CR7 then takes away space from the other guys... He doesn't give a damn, he just wants to score goals. Portugal has a lot of talent but there is this enigma Cristiano Ronaldo who thinks he is the best. He's gone for me now."
