Atletico Madrid president Enrique Cerezo has played down talk of a deal for Sevilla striker Kevin Gameiro.
The Frenchman has been linked with Atletico this week.
But Cerezo says: "Gameiro is a good player, we always want the best players, but we have already signed a great one in Griezmann."
Many names have been linked to supplement the existing attack of Griezmann, Angel Correa, and Fernando Torres, such as Mauro Icardi and Diego Costa.
"We're working on [transfers], be patient" the president responded when asked about a new striker.
"Everything is possible, our staff are working on signing a good player to fill that position."
