Aguero announced his intention to leave the Vicente Calderon at the end of last season and has been the subject of transfer talk involving Real Madrid, Manchester City and Juventus, but he remains an Atletico player.
Forlan and Aguero will come face-to-face when Uruguay meet Argentina in the quarter-finals of the Copa America on Saturday, with both due to sort out their futures once the continental competition has been concluded.
"There are lots of rumours," Forlan said. "I have two years left on my contract and I want to stay, as I have always said - I have always felt comfortable."
Nevertheless, Forlan, who has attracted interest from Besiktas, Galatasaray and Tottenham, among other sides, admits he could be forced out of the club after falling out with former coach Quique Sanchez Flores last season.
"There are more people who want me out than there are people who want me to stay," he said.
But while the Uruguayan could yet continue at Atletico, he feels Aguero should be allowed to move on.
"He said he wasn't going to stay and his statement is there [for all to see]," he said.
"It's a shame because he is an important player; the two of us knew each other well and we formed a very good partnership, but I'm not going to analyse it and say if it is right or wrong - if he is really happy with the decision he made, then we have to accept it and wish him good luck."
