With 49 competitive goals between them this season, Forlan and Aguero have formed a hugely prolific partnership in their first campaign together and that has inevitably led to speculation about whether Atletico will be able to keep them.
But Forlan said: "The two of us have signed contracts. I am sure that we will continue. I feel very happy in a lovely city and a great club,"
The 19-year-old Aguero had attracted a huge amount of reported interest from other clubs this season after notching 26 goals already - three more than Forlan.
Like his fellow South American though, the Argentinian striker insists his future lies at the Vicente Calderon.
"I am very well and very happy here. I am not thinking of leaving," Aguero said in AS.
"It is true that with Forlan everything has gone very well this season and we understand each other very well. I hope that next season we can be even better together."
