Athletico Bilbao coach Marcelo Bielsea has refused to give anything away over the future of striker Fernando Llorente.
It was reported earlier this week that the 27-year-old had turned down a new lucrative contract with the Spanish club.
"It's a private matter not yet resolved," Bielsa told reporters. "I want the best for the team, the player and the club."
Manchester City, Manchester United and Juventus are all thought to be interested in Llorente.
