Tottenham Hotspur still believe they can sign Hamburg forward Heung-Min Son during the summer, despite suggestions the German club will offer him a new contract before the end of the week.

The South Korea international has long been linked with a potential move to White Hart Lane, with the Evening Standard reporting that Tottenham have continually scouted the versatile forward throughout the season.

Son has once again excelled this season, scoring nine goals in his 27 league appearances, but Hamburg have endured a difficult campaign and will struggle to secure European football as they sit in 11th place with just six games remaining.

With Hamburg struggling, both for form and financially, there is a growing belief that a number of their top performers may well leave at the end of the season, including Son who currently has just over 12 months remaining on his contract.

The 20-year-old joined the Bundesliga side when he was just 16 and has managed to become an important member of the first team, missing just one league game all season.

Hamburg are desperate not to lose the exciting young forward with reports suggesting that they are prepared to offer him a weekly salary of around £45,000-a-week. However, the Standard believes that Spurs still feel that they can persuade Son to force through a move to the Premier League.

Should Tottenham manage to secure Champions League football then they would certainly be an enticing prospect for Son who has yet to play any form of European football.

The north London club have long been interested in the forward, having reportedly first sounded out the possibility of signing Son when they sold Rafael van der Vaart back to the German club last summer.

Andre Villas-Boas is short of attacking options with just two senior strikers at the club in Emmanuel Adebayor and Jermain Defoe. Gareth Bale has been deployed as a forward this season but there is a feeling that they are light in attack.

With reported interest from Italy, Spain and other German clubs, it seems it would not be easy for Tottenham to secure his services but should be refuse a new contract then it would certainly help their cause.

While they would hope that they are an attractive destination, former star Van der Vaart has urged his teammate to remain with Hamburg as he is guaranteed regular first team football.

"I think for Sonny it would be better to stay here for now. I'm not just saying that because the boy has been in outstanding form," said the Dutch midfielder. "It's the first very good season in his career, he doesn't have to make a change. At the biggest clubs, you can easily end up on the bench."
