Despite the player's wishes, Atletico Madrid are famously difficult negotiators and have reportedly pointed toward an astronomical €500 million (£431m/$569m) release clause.
Aguero acknowledged that the final decision remains in the hands of the Rojiblancos hierarchy, though he suggested that their firm public stance might simply be part of the negotiation process.
“With that release clause, the decision rests with the club. The club will decide whether or not to sell you - and, being honest, he ended up telling the club the truth - and that is the best approach,” the former player said.
He added that no club wants to admit they are willing to lose a star, but keeping an unhappy player can often lead to detrimental effects on the dressing room environment.
