The Bavarian club seems close to signing Schalke midfielder Leon Goretzka ahead of the summer and that could pave the way for the Chile star to depart.
Vidal, 30, told Kicker: “I'll stay here until the summer, then we'll see what happens."
Blues boss Antonio Conte was asked about a possible reunion with the midfielder late last year.
He said: “I must be honest, it's not right to talk about a player of another team.
“Especially if you try to link this player with us. July is very far."
