Atletico chief executive Miguel Angel Gil Marin says they're prepared to sell Radamel Falcao this summer.
Falcao is wanted by AS Monaco, Chelsea and Manchester United.
"Atletico knows how to change good strikers," Marin told Sky Sports. "Fernando Torres, Forlan, Aguero and now Falcao.
"We don't know who exactly will be the next one but we know Atletico will have a strong team next season.
"Before the start of the season we talked with the player and we promised him that if he kept the same performance and helped us to the UEFA Champions League, Atletico would help him.
"Every decision that he takes, Atletico will be with him."
