Real Madrid are reportedly lining up a summer swoop for the 28-year-old, with Zinedine Zidane making Mane his top transfer target.
Liverpool do not seemingly have any intentions of selling Mane, though Balde has suggested his international colleague may have other ideas in future.
"It depends on many things," Monaco star Balde told AS. "I don't know what his decision is. In a year or two, you may want to change.
"I don't think he wants to be there forever. He is a smart boy and he knows what is good for him and what he has to do. But in Madrid they are giving out many names."
