Heung Min-son's agent insists he will not discuss his future until the end of the season, after being linked with a move to the Premier League.
Reports in Germany claim that Newcastle United are closely following the 19-year-old South Korean international.
The young forward has been with Hamburg since he was 16, and is the club's youngest ever goalscorer.
He has emerged as one of their brightest young talents, which has seen him attracted interest from around Europe.
Newcastle are now said to be monitoring Heung, who has two-years left on his current deal.
But with Hamburg still embroiled in the relegation battle in Germany, his agent says they will not discuss his future until the summer.
"We will not deal with such things until the end of the season," Thies Bliemeister told Bild when asked about Heung's future.
"The only thing important as this time is Hamburg's place in the league."
