Manchester City manager Pep Guardiola says Leroy Sane's future at the club is "not in our hands".
Bayern Munich are "working very hard" to secure their "dream signing" of Sane, according to head coach Niko Kovac.
Sky in Germany understands Bayern held positive discussions with Sane's representatives earlier this week over a potential move to the Allianz Arena.
But Sky Sports News understands City have no interest in selling Sane and are yet to receive an official bid for the Germany winger.
"He did a good game, especially in the second half. He is a guy who we appreciate, I like him a lot," said Guardiola after City's 6-1 win over Kitchee in Hong Kong.
"I think he can be better. Two times, three times I said: we want him to stay.
"That's why he has an offer to extend his contract. It's not in our hands.
"The agreement is good and if he wants to leave, I'll be sad. Hopefully, he stays."
