Hamburg coach Thorsten Fink has said he is eager to keep South Korea star Son Heung-Min at the Bundesliga club while both Premier League giants Liverpool and Arsenal are reported to have shown interest.
The 20-year-old Son, who has made 12 international appearances, has been in impressive form this season and is the club's top-scorer with five goals in ten games.
With Son's contract set to expire in June 2014, Fink says he wants to keep his star forward to help build a title-winning team, but Son was evasive last week when asked about his future with the north German club.
"We want to achieve something with Son," Fink told German Sky Sport News.
"I think it would be better for his sporting development, if he stayed and played with us.
"When anyone plays well, there is of course always a bit of transfer speculation about him.
"Ultimately, Son must know that we want to build something here and we have kept hold of players who want to also achieve something."
Hamburg are at Freiburg on Saturday and are currently ninth in the league having lost 3-0 at home to Bundesliga leaders Bayern Munich last weekend.
