A host of Premier League clubs are chasing Martin Stranzl.
The Daily Mail says Stranzl has put West Ham United, Everton and Fulham on alert after telling Spartak Moscow he wants to quit the club.
The former Austria centre half has fallen out of favour with Valery Karpin over the last six months as the Spartak coach has struggled to shuffle his foreign players to meet Russian Premier League rules.
The 30-year-old attracted interest from England last year but was persuaded to stay in Moscow. However, he has now asked to be released from his contract a year early.
