Borussia Dortmund general manager Michael Zorc will not be drawn on speculation linking the club with a move for Kevin de Bruyne.
The midfielder has spent the season on loan at Werder Bremen from Chelsea, and has acquired several suitors after impressing in the Bundesliga.
The Belgium international has yet to make a first-team appearance for the London club, and that situation looks unlikely to change next season.
That has led to rumours that he could be sold in the off-season, with Dortmund thought to the front-runners for the ex-Genk player's signature.
However, Zorc, while admitting he thought De Bruyne was a talented football, would not be drawn on reports of a possible move.
"I am not going to either confirm or deny this (agreement)," he told Bild.
"Kevin de Bruyne is under contract with Chelsea FC, he is a good player currently on loan at Werder Bremen."
The player himself conceded he did not know where he would be playing season.
"I am receiving a lot of offers for next season," De Bruyne added.
"But I am not yet aware where I will play next term."
De Bruyne has scored eight goals in 32 league appearances for Werder Bremen this season.
