Werner has also been linked with Liverpool.
And Rangnick says: "I would not be so sure that Werner will actually go to Bayern.
"If Bayern were absolutely sure about Timo, they would have already officially contacted us with a request.
“Anything else would be unusual for Bayern, especially since we have a good relationship with them.
"Our position has not changed: we do not want him to go into the last year of his contract without an extension."
