Thing is, that Atletico know they are bound to lose Aguero whether it is to Juventus or City or Real. While we are well aware of that, we are also aware that Atletico had a firm eye on Rossi to replace Aguero. So Marrotta maybe playing an interesting game here, closing on Atletico's primary target, while they full well know they're going to lose Aguero, and they might not want to risk losing his replacement too. Might coerce them to come to the negotiating table and lower their demands closer to Juve's offering in the process. Also because it would mean not only selling Aguero to Juve but also freeing up Rossi again. Conspiracy theory maybe but could be an angle to the situation.
