Atletico Madrid deny offering Forlan to Real Madrid
However, Atletico chairman Enrique Cerezo insists there is no substance in the story.
"Every time there is something, I have never had a problem talking about it," he said.
"In the case of Forlan, nothing happened, we don't know anything."
Forlan was linked with a move away from the club over the summer after enhancing his reputation with a fantastic World Cup, where he was voted player of the tournament.
He has made a disappointing start to the season and rumours have surfaced regarding a possible rift with manager Quique Sanchez Flores.
"There is no problem between Quique and Forlan," said Cerezo. "Their relationship is perfect. When (Forlan) starts scoring goals, no-one will say any more."
