Pep Guardiola says Leroy Sane's future is out of Manchester City's control.
The German is being tempted with a return to the Bundesliga with Bayern Munich.
City have offered Sane a contract extension, but Guardiola admits the 23-year-old will decide if he wants to join Bayern.
"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."
