After Brazil's 3-0 Copa America win over Bolivia, Luis told Marca: "I'll say to my friends at MARCA and everyone else that you'll know [about my future] after the Copa America.
"There's a chance that I'll stay and there's a chance that I'll leave.
"Out of respect for the national team, it's not the moment to negotiate. I will sit down with the club and my representatives after the Copa America and we'll see what I have to do.
"But you know Atletico is the club in my heart and where I've spent the best years of my life."
