Thiago Alcantara, David Alaba, and Jerome Boateng have yet to sign new contracts which will hold them beyond next year at Bayern Munich, but Hansi Flick wants them all to stay.
In recent years, speculation has swirled around various main players in Bavaria, with some contracts expiring at the end of the season 2020-21.
Reports have suggested that Thiago was in club talks about a new deal, but that Bayern is increasingly frustrated by the prolonged silence of the Spaniard.
That has led to suggestions that Thiago might be looking for a way out, and if he desires to leave, Bayern will have to unload him in the months ahead or risk losing him next year on a free transfer.
As for Boateng, the experienced central defender also has a season left on his current terms and has been mooted as potential destinations despite enjoying an impressive resurgence under Flick, Paris Saint-Germain, and Hertha Berlin-his first club.

Alaba is in a similar role with his contract but Flick has expressed a desire for the trio to remain with the champions of the Bundesliga.
“Thiago’s an exceptional player, an incredible player in football. He brings a great level of play to every unit and is very smart. I want him to live here. He knows that, and the club. I want him and Alaba to support us next year. We ‘re in good spirits that it can work out but you never know how it will turn out in the sport. They ‘re top stars, top players. David and Jerome are doing very well, he [Boateng] is in good shape, which is the foundation on which we are so strong defensively,” he told reporters Friday.
The flick also needs loan players from Bayern, such as Ivan Perisic and Philippe Coutinho, to remain on at least until the end of the last stages of the Champions League in August.
But he admits both will have to return respectively to their parent clubs, Inter and Barcelona.
