Tottenham Face Competition From Dortmund In Race For Bundesliga Forward - Report

Tottenham Hotspur's hopes of signing Hamburg's Heung-Min Son have been dampened amid reports that Borussia Dortmund are considering a move for the forward.

Andre Villas-Boas' side have been heavily linked with a move for the South Korean international throughout the season and have already sounded out discussions with the Bundesliga side regarding a move this summer, the Evening Standard report.

Hamburg director of sport Frank Arnesen has previously warned Son's list of suitors that the club are looking to tie the forward down to a longer contract, with his current deal set to expire in the summer of 2014. But the warnings have not deterred Spurs, or Champions League finalists Dortmund, who have joined the race after suffering blows to their own attacking options.

Despite their European triumph over Real Madrid last week, Jurgen Klopp's Dortmund were rocked by the news mid-week that Mario Gotze will join Bayern Munich at the end of the season after having his buyout clause met by the Bavarian giants.

Robert Lewandowski, who has proven so integral to the club's ambition over the past two years, is also likely to leave this summer as he approaches the final year of his contract. With Manchester United and Bayern vying for the Pole's signature, the club are in need of attacking reinforcements and the Standard suggest that Son may be the man Dortmund consider.

Andre Villas-Boas and Daniel Levy are also keen to strengthen Tottenham's attacking options. Despite Gareth Bale and Jermain Defoe racking up 39 goals between them in all competitions this season, the disappointing form of Emmanuel Adebayor and speculation regarding the Welshman's future at the club suggests moves will be made in the coming months.

21-year-old Son has been enjoying a breakout season for Hamburg this campaign, hitting a respectable 11 goals in 28 appearances for the club. Speaking last February, the forward's agent confirmed Premier League interest in his client.

Son's agent Thies Bliemeister said: "A transfer next summer? He has signed a new contract with Hamburg SV extending it for one year, but there have been many offers for him as from Manchester United and Chelsea."
