Hamburg determined to keep hold of Liverpool, Spurs target Son
Hamburg chief Frank Arnesen insists striker Heung-Min Son is not for sale.
Son bagged a brace in Hamburg's 2-1 Bundesliga win over Mainz on Saturday, taking his tally to 11 goals in 28 appearances this term.
Tottenham and Liverpool are amongst clubs following the South Korean.
"He still has a year to go on his contract and we haven't had any offers from other clubs," said Arnesen.
"We are at a good stage with him and his contract extension so I am positive that we will extend with him for the long term.
"We have to ensure that we extend his contract as quickly as possible so that he can be settled."
