Hamburg chief Frank Arnesen says they're prepared to sell striker Heung-Min Son.
"Of course we have a target where we accept a bid," said Arnesen to the Hamburger Morgenpost. "Sonny is a young and very talented player. We have the ambition to discuss a new contract and are in the position to offer him a good deal.
"I am sure that we will find a solution and we can retain him longer than his current contract, which runs until 2014."
