Bayern Munich coach Jupp Heynckes insists Artur Vidal is valued inside the club.
Linked with Manchester United and Chelsea, the midfielder admits he could leave at season's end.
Heynckes said: "Arturo Vidal has a contract until 2019.
"For me he is a fundamental player in our team.
"He is playing at a very good level, he's just a class player, a player who is hugely experienced, a player who is on point when you need him.
"My opinion is that he is very important. I consider him a fantastic footballer. The player has to decide if he wants to stay here, and the club too."
