Hamburg manager Thorsten Fink has stated that the club may be forced to sell exciting young striker Son Heung-min at the end of the season if the right offer arrives.
Son has been heavily linked with a move away from the Bundesliga side, with Sky Sports suggesting that Arsenal and Tottenham have been monitoring the situation closely as they consider summer bids for the striker.
It is growing increasingly likely that the South Korea international will exit Hamburg at the end of the season as general manager Frank Arensen recently revealed that he would be sold if he refuses to sign a new seal.
The 20-year-old, who has scored 11 league goals this season, has just over 12 months remaining on his current deal and it seems Hamburg would rather cash in this summer, than lose him for nothing at the end of the following season.
"If Heung-min Son is not signing a new contract and makes up his mind to definitely leave, and given a concrete offer from an interested club, then we would be forced to sell," Fink told German newspaper BILD.
"In a situation like this we would be unable to do anything else as we would be unable to keep hold of him."
Over the last week there have been reports suggesting that Hamburg would accept an offer in the region of €10million as they are desperate to bring in funds to help ease their financial problems.
The figure is unlikely to deter Arsenal or Tottenham who have both been linked with numerous forwards over the course of the season.
Spurs missed out on signing Interncaional striker Leandro Damiao in January and with Emmanuel Adebayor struggling for goals, it is expected that Andre Villas-Boas will look to strengthen his options in the summer.
However, Tottenham may face competition for Son's signature from Arsenal who will be hoping they can remain above their London rivals and prevent them from finishing in the top four.
Should Arsene Wenger's side achieve this feat then the lure of Champions League football may play a factor in trying to convince Son to move to the Emirates.
