Hamburg's South Korean sensation Son Heung-Min has reportedly turned down a contract with the German club, alerting north London rivals Arsenal and Tottenham Hotspur to his availability.

The 20-year-old forward has received plenty of admiration from Europe's elite, with Manchester United and Chelsea both showing interest, but Arsenal, Tottenham and German clubs Bayer Leverkusen and Borussia Dortmund are thought to be most eager to secure the South Korean's services.

The Daily Express has reported that Son has turned down a three-year contract extension at HSV, which would keep him at the Imtech Arena until 2017.

His agent, Thies Bliemeister, told German newspaper Die Welt: "We are under no pressure from HSV.

"Everything has to fit. We have clear ideas, and first of all they centre on Son's development.  If his development is right, he will earn enough anyway."

Son has nine goals in 23 games in the Bundesliga this season, including a brace in a shock 4-1 victory over Borussia Dortmund earlier in the month. His tally has propelled Hamburg to seventh in the table, on the fringes of Europa League qualification.

And the 20-year-old already has 12 caps to his name, featuring in five of South Korea's six World Cup qualifying games so far.
