Hamburg sporting director Frank Arnesen has accepted the club have a fight on their hands to keep youngster Son Heung-Min this summer.
The South Korean forward is highly rated by the Bundesliga outfit and the 20-year-old’s performances in the German top flight this season have not gone unnoticed.
Son’s contract expires at the end of next season and, although Hamburg are trying to tie down the youngster to a new deal, Arnesen has admitted they might be forced to sell, with the likes of Arsenal, Tottenham and Borussia Dortmund believed to be waiting in the wings.
He told Bild: “Heung-min Son is under contract with our club and we are talking to him about signing a new contract.
“Obviously we will have to sell him, if he does not sign a new deal with our club.” (Goal)
