Atletico reported Barca to FIFA over their alleged pursuit of the France striker, who is said to have rejected the advances of Jose Mourinho's side in pre-season.
And Torres, who is keen to extend his own deal which expires at the end of the campaign, believes Atletico can retain Griezmann's services.
"Atletico can sign and retain the world's best players, as we have shown," he told Radio Marca.
"Griezmann is still here at the club and we all want him to stay of course, but you would have to ask him on his future and what he wants to do next."
Griezmann, who has scored five goals in La Liga so far this season, has a contract at the Wanda Metropolitano until June 2022.
On his own future, Torres said: "I want to stay here forever, I have a half year on my contract, and it does not depend on me."
Atletico are currently second in La Liga, six points behind leaders Barca, and take on Espanyol on Friday.
