Hamburg's Sporting Director Frank Arnesen says the club will do everything to keep South Korea star Heung-Min Son, with a new deal forthcoming.

Son has impressed in the the Bundesliga this season and scored twice in Hamburg's 2-1 win over Mainz on Saturday, taking his tally to 11 goals in 28 appearances.

Son, who arrived from FC Seoul in 2008, has just over a year left on his current deal but Arnesen is keen to sort out new terms and ward off interest from other clubs, with Tottenham reportedly leading the chase.

"Son, with his 20 years, is one of the players we would really like to keep hold of," he told Sky Sports. "We are willing to push ourselves to our pain barrier for him.

"He still has a year to go on his contract and we haven't had any offers from other clubs. 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."

Son has been linked with a move to some of the top German sides, while scouts from Serie A, the Premier League and La Liga have also shown an interest in him this season.
