Tottenham and Chelsea are following Hamburg striker Heung-Min Son.

Sport1 says both Premier League clubs had scouts check on the 20 year-old South Korean in action against Werder Bremen last week.

Son is inside the final 18 months of his current deal and HSC are eager to open talks about a new deal.

"I have a contract with HSV until 2014. We have to wait and see what the talks bring," said Son.
