Tottenham have reportedly moved ahead of north London rivals Arsenal, as well as Manchester City and Manchester United, in the race to sign Hamburg forward Heung-Min Son in the summer transfer window.
According to the Evening Standard, Spurs have been keeping tabs on the 20-year-old South Korean, although any proposed move could be scuppered by Hamburg's plan to offer the player a new contract.
The interest of Spurs in Son dates back to negotiations between the club and Hamburg over the sale of Rafael van der Vaart last year, and Andre Villas-Boas is reported to have shown a greater desire to sign the youngster than any of his counterparts.
This has reportedly placed Spurs above Arsenal, Manchester City and Manchester United in the running to sigh the South Korea international, with Son's ambition to secure a transfer to an English club when he leaves Hamburg.
Spurs, however, may have some difficulty in signing Son this summer, as may Arsenal, Manchester City or Manchester United should they formalise their apparent interest, with Hamburg set to offer him a lucrative new contract.
The Bundesliga club are reported to be willing to pay Son £45,000-a-week in a new long-term deal, which could included a stipulation that allowing him to be sold in 2014 should the conditions of the contract be met.
Son, meanwhile, has been urged by Rafael van der Vaart to stay at the Imtech Arena and resist the temptation to leave Hamburg for the Premier League at the end of this season.
"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," the former Spurs star said, as reported by the Evening Standard.
"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."
