Sao Paulo: Brazil coach Dunga wants Ronaldo to leave Real Madrid. "It's gotten to a moment where he needs a new perspective, a new challenge," Dunga told Globo TV on Wednesday. "Brazilian players need to be happy where they are, and what we see now is that he isn't happy, and he isn't because he is not playing."Ronaldo, who hasn't been picked to play for Real Madrid since January 7, is reportedly nearing a deal to move to Italy's AC Milan. The 30-year-old striker said on Monday his difficulties with coach Fabio Capello seem set to force him out of the Spanish club.Dunga hasn't summoned Ronaldo to the national team since taking command of the squad after the World Cup. Brazil was eliminated by eventual runner-up France in the quarterfinals in Germany, and Ronaldo played poorly during most of the competition.Carlos Alberto Parreira, Brazil's coach in the World Cup, said Ronaldo is capable of returning to form."If he wants to become the old Ronaldo again, he can," Parreira said. "But he needs to change his behavior, he needs to focus on soccer at all times."Ronaldo, who helped Brazil win the World Cup in 1994 and 2002, is under contract with Real Madrid until June 2008. He has seven days remaining in the January transfer window to switch clubs this season.
