"There are no enquiries," Watzke told ZDF. "However, I'm aware of the interest in the player, which is normal [considering his quality]. We're in a good situation and we're not forced to sell players.
"When the offers come, we will talk to Robert, but there's a good chance he decides to stay with us. We are playing Champions League and have a good chance to qualify again for next season, I just don't see the necessity to let go any players."
