Dortmund Step Up Chase For Tottenham's €10m Striker Target – Report

Borussia Dortmund are hoping to do their business early in the summer transfer window and are believed to be stepping up their pursuit of Hamburg striker, and reported Tottenham target, Son Heung-Min.

Son has starred for Hamburg since moving into the side's senior line-up in 2010, and this season after scoring 12 goals in 30 appearances he has put a number of clubs on alert to his services.

Tottenham are believed to be the main club in England interested, though as Dortmund look to a season that will be without Mario Goetze and possibly Robert Lewandowski, Talksport are reporting that the German club are now starting to make their interest in the hitman concrete.

Spurs are in desperate need of strikers this summer, with Jermain Defoe and Emmanuel Adebayor the only senior forwards on the club's books.

Gareth Bale has stepped in to fill the gap up front this season, but his own future with the club is uncertain as the likes of Real Madrid circle, while the club's reliance on the Welshmen came to the forefront when he was injured.

Son can offer both current talent and potential to grow in the future, with the 20 year old having earned a reputation as one of the best young prospects in Germany over the last three years.

And the youngster, who has been nicknamed the 'Korean Muller', has also received special praise from German legend Frankz Beckenbeauer, with the former star saying: "He's a super player. I really like the way he plays: Fast and dynamic.

"He does not only score beautiful goals, but also makes them."

Tottenham would reportedly be able to sign the striker for just €10 million, which could make him an attractive proposition as this is a relatively small sum for a forward.

But with the club unable to guarantee Champions League football until the end of the season, Dortmund could steal the march on the north London side and begin talks now.
