West Ham are interested in signing Werder Bremen centre-back Jannik Vestergaard, report German magazine Sport BILD.
Vestergaard, 23, is a Danish defender who has five international caps for his country plus one goal, and has been a regular starter in the Bundesliga this season.
Danish outlet Bold.dk also run the reports, adding that Werder Bremen sporting director Thomas Eichin concedes he may find it tough to hang onto the defender, who has already captained the club.
Eichin is quoted: "With us, all players in principle for sale if there is an offer that we, for business reasons can not refuse, then we talk about it."
Vestergaard stands tall at 6 foot 6 and has a contract with Werder Bremen which currently runs until 2018.
Premier League competition
West Ham are not the only Premier League side to show an interest in Vestergaard over the last 12 months. Just last week Bild reported, as relayed by Fussball Transfers, that Tottenham Hotspur are monitoring the defender.
The Northern Echo reported back in August that Newcastle had an offer for Vestergaard turned down, believed to be in the region of £9 million, but Rafa Benitez's side will surely be out of the race if they suffer relegation.
Bild also reported last May that Roberto Martinez's Everton were showing an interest in the defender.
