Hamburg General manager Frank Arnesen has conceded that in-demand forward Heung-min Son could be sold if a suitable offer is made.
Son has a bourgeoning reputation as one of the best young talents in Europe, and has scored 16 times in 65 appearances for Hamburg since making his debut for the German club in 2010.
Tottenham, Arsenal and Liverpool have been linked with a move for the 20-year-old, who was in action for South Korean in their 4-0 international friendly defeat against Croatia at Fulham's Craven Cottage last night.
Former Tottenham director of football Arnesen admits that Son would be allowed to leave Hamburg for the right price, but remains confident of tying him down to a long-term deal.
"Of course we have an acceptance limit," he told Hamburger Morgenpost.
"But Sonny is a very young and great talent. We have the ambition to sign new terms with him and will be in a position to hand him a good deal.
"I am sure we can find a solution to keep hold of him for longer than the end of his current deal (which expires in June 2014)."
Spurs were reportedly ready to make a bid for the talented youngster in January, however a deal failed to materialise.
Former Tottenham midfielder Rafael Van der Vaart, now with Hamburg,says he understands the north London club's interest in his team-mate.
“Spurs are always searching for the best young talent, that is why every year they are near the top,” he was quoted as saying last month.
Van der Vaart has also previously spoken out about Liverpool's interest in Son, urging him to resist the temptation of a move to Anfield in order to develop his career in Germany.
