Diego Simeone believes Atletico Madrid can convince Antoine Griezmann to remain with the club this summer.
Last summer, Griezmann considered a move to Manchester United before signing a new deal with Atleti.
Barcelona has recently been linked with Griezmann and are prepared to pay his €100 million release clause.
"We want the best for Griezmann," Simeone said. "We must make him see that this team can keep growing, I hope we can do that. That things are real, not just words. If we keep fighting with Barcelona, and until the final of the Europa League, we will see that each year we do something good. We must give him all the tools so that, when he needs to decide, he inclines towards staying with us."
