Manchester City expect to learn on Friday if their offer for Marlos Moreno has been successful.
City and Fiorentina have lodged bids with Atletico Nacional for the Colombia winger.
Eladio Tamayo told Firenzeviola.it: "On Marlos Moreno, no decision will be taken until Friday. On that day there will be a meeting between us and Atletico Nacional to discuss the offers that have arrived for the player and a choice will be made.
"The interest of Fiorentina and Manchester City? At the moment all the rumors are just speculation because the player, after concluding the Copa America, is focused on the Libertadores with his team.
"I repeat, Friday will be a final decision on Marlos Moreno and it will be announced by his club."
