Atletico Madrid president Enrique Cerezo has insisted that there is no deal in place for Chelsea to sign Diego Costa in the summer.
The striker has been the subject of intense speculation in recent weeks, especially after the 25-year-old fired Madrid to the Champions League final, knocking out the Blues in the process.
However, Cerezo has furiously denied those rumours.
"Chelsea? We do not know when these [remaining] games are so important," Cerezo told Mundo Deportivo, as his side prepare for a close La Liga title run-in and Champions League final.
"We do not want to destabilize the team and we can talk about this later. I can say that there is something, not officially, from another club regarding any of our players.
"They are not heading to any other team.
"If the question is "Is there an agreement for Costa," then we have not heard anything."
Costa has became one of the world's most sought-after forwards after notching an impressive 27 goals in league action this season. Only Lionel Messi and Cristiano Ronaldo have scored more than the powerful star.
His goals have fired the Vincente Calderon outfit to the top of La Liga, as they bid to become to first side in 10 years to break Barcelona and Real Madrid's dominance. If Diego Simeone's side win their last two games, they will be champions for the first time since the 90s.
Meanwhile Chelsea's chances of lifting the Premier League took a massive blow as they could only manage a goalless draw at home to Norwich City.
The story of their season has been beset by a lack of goals from their attacking trio of Fernando Torres, Demba Ba and Samuel Eto'o. Therefore the need for Costa is plain to see.
