The 27-year-old’s brother and agent has revealed he has played his last game for Velez Sarsfield in Argentina and deal with the Hammers is almost done.
Rolando Zarate said: “We have almost everything sorted out with West Ham, they asked him not to play against San Lorenzo but he wanted to play.
“Mauro Zarate and his family’s love for Velez is huge, but the club receive a good financial compensation.”
The striker impressed during a loan Birmingham in the 2007/2008 when current West Ham owners David Gold and David Sullivan were at St. Andrew’s.
Gold and Sullivan have both been long-term admirers of Zarate and are thought to have orchestrated a move to bring him back to England without the say of manager Sam Allardyce, after a statement by the club yesterday suggested the board had relinquished all control over transfer dealings at Upton Park.
Zarate finished as the Argentine top-flight’s leading scorer with 18 goals in 28 games following a brace in a 2-0 win over San Lorenzo on Tuesday.
It is believed he will arrive in England later this week ahead of a medical at the Hammers, despite interest from other clubs in the Premier League and across Europe.
