Pep Guardiola says he wants Leroy Sane to stay at Manchester City but admits the decision is out of his hands.
Sane, 23, has two years left on his contract but is yet to commit to talks over an extension.
The Germany winger scored twice in City's 6-1 win over Hong Kong side Kitchee in their latest pre-season tour game - with David Silva, Raheem Sterling and Spanish youngsters Nabil Touaizi and Iker Pozo also netting.
Bayern Munich want to sign Sane.
"We want him to stay and there is an offer waiting to talk with his agents to extend the contract," said Guardiola. "It is not in our hands. He has to decide. If he wants to leave, he can do it but we will be sad.
"Hopefully he stays."
City the good tourists
After the furore that followed criticism of their 'arrogance' in Chinese State media after they played in the Premier League Asia Trophy last weekend, City have been on their best behaviour in Hong Kong.
This included every player shaking the hand of Kitchee's long-serving South Korean defender Kim Dong-jin as he was substituted in the final appearance of a career that brought him 62 international caps. It is fair to assume none of the City squad had ever heard of him. Manager Pep Guardiola presented him with a personalised shirt as he reached the touchline, which went down well.
As it was 29C at kick-off, with humidity levels of 86%, it was the type of pre-season game that had little value, other than to serve City's wider commercial ends as they slowly turn their success on the field into an expanding - monied - supporter base.
This four-match trip was not made easier by a mistake with the arrangements for City's initial flight to Shanghai which meant they did not arrive in China until 15 July, 48 hours behind schedule.
Guardiola accepts it is not the ideal preparation for the start of City's Premier League defence at West Ham on 10 August.
He said: "With situations I can't control, I adapt. We are not going to go to West Ham saying what a disaster it was to be here because of the heat and humidity.
"It is not good. I would have preferred to do it another way but it is what it is. We have to be here, so we do the best we can."
A crowd of 20,926 was present at the Hong Kong Stadium for the game. A banner was raised backing the protests that have been taking place in the territory against growing Chinese influence.
Fans also chanted anti-China messages.
"Hopefully a solution can be found," said Guardiola, who has made a visual display of Catalan dissent against the Spanish government in recent years by wearing a symbolic yellow ribbon.
"Sometimes this kind of thing happens in society."
City fly to Japan tomorrow ahead of their final tour game against J-League side Yokohama F Marinos, who are also part of the City Football Group, on 27 July. They play Liverpool at Wembley in the Community Shield on 4 August.
