Kai Havertz has made quite a name for himself as he burst onto the scene for club and country this season, and Bayer Leverkusen manager Peter Bosz has admitted the decision over Havertz's future is out of his hands.
A number of clubs including Liverpool and Manchester United are said to have shown interest in signing the German international.
Leverkusen boss Bosz said he would like to keep him for a few more years, but appreciates that may be a challenge, per Sport Bild.
"Of course I would like to keep him, just as I would have liked to keep Julian Brandt, for example," he said, referencing the winger who left Bayer for Borussia Dortmund in May.
"Kai is only 20 and still has room for improvement. I can help him there. But it is like this, at the end the player himself must feel when he is ready for the next step. Nobody can decide that for him."
Speaking on a possible move to Bayern Munich, Havertz told Bild, “I really don't know yet whether Bayern is the next and right step for me.
“I also don't know whether foreign countries would not be more suitable for me. I really don't think too much about it at the moment. I think there were a number of reasons why,” when asked about his failed move in the summer transfer window."
“But I'm happy to be here and stay in Leverkusen for another year. We'll see what will happens next summer.”
