Diafra Sakho’s proposed £3.5 million move to West Ham United is in danger of collapsing after the forward’s current club claimed the Irons have changed the terms of the deal agreed between the two parties
The 24-year-old was left out of Metz’s Ligue 1 clash with Lille at the weekend with a view to completing a medical with the Premier League side.
But, in a statement released by the French team, Metz have claimed West Ham have shown a "clear lack of respect" which is "unacceptable" to both the player and club, after the Hammers reportedly attempted to change the terms of the deal, proposing that they sign the player on loan rather than permanently.
"The English club unilaterally decided to propose a loan deal with an option to purchase, instead of a permanent deal, which does not correspond to FC Metz’s expectations and contradicts all the terms that had been agreed last week between the two clubs," the statement read.
"As a result, FC Metz reserve the right to approach the international sport court and assert their rights and defend their interests."
The comments are a blow to Sam Allardyce’s preparations for the new season, with the West Ham boss keen to conclude a deal for Sakho ahead of the start of a Premier League campaign that sees his team kick things off against Tottenham at Upton Park.
West Ham have been pursuing the Senegalese forward for several months now after the 24-year-old netted 20 goals in 37 games for Metz last term to help them make a long-awaited return to Ligue 1.
The London club have been busy recruiting a number of new strikers this summer with Enner Valencia and Mauro Zarate having both arrived at Upton Park ahead of a new campaign in which West Ham will be expected to improve under Allardyce.
