Werder Bremen's Brazilian playmaker Diego wants to play for Real Madrid but the Spanish champions have yet to declare any interest, his father and agent told a Spanish sports daily published on Tuesday.
"Diego would definitely like to play for Real Madrid," Djair da Cunha told the newspaper Marca.
Real Madrid "is a great club, a very important club," he said. "But I am his only legal representative and I can assure you that for the moment there is nothing."
The German press recently linked him with Real Madrid for next season.
"If Real Madrid is interested, it must say so," said the father of Diego Ribas da Cunha. "But I think that would be better at the end of the season. Now is not the time."
"It does not depend on us," he said, noting that his son has a contract with Werder Bremen until 2011.
Diego, 23, joined the Bundesliga club from FC Porto in 2006, and has scored 10 goals in the German championship this season.
If he were to sign for Real Madrid, he would team up with Robinho, his former team-mate at Sao Paulo club Santos and now in his third season with the Spanish champions.
The pair formed a dynamic and fresh-faced partnership at Santos, helping the team win the Brazilian title in 2002 and 2004 and reach the Copa Libertadores final in 2003.
