Atletico Madrid manager Diego Simeone has hinted the club may find it difficult to keep hold of Antoine Griezmann.
France forward Griezmann has excelled since joining Atleti from Real Sociedad in July 2014 and has netted 43 goals in 81 appearances.
Chelsea, Real Madrid and PSG have all been linked with the 24-year-old, who is under contract until 2020.
Simeone said: “The sporting directors have been speaking to him directly, with those close to him, in order to work out what’s best for him and the club.
“Of course he’s a very important player for us, but we can’t hold him here with chains.”
