West Ham have agreed a fee to sign Paraguay international Fabian Balbuena, according to the defender s current club Corinthians.
The Brazilian champions confirmed Balbuena would travel to London to complete the deal after his release clause was met.
An international since 2015, the 26-year-old had also been linked with Dutch outfit Ajax and Portuguese heavyweights Sporting CP.
But he now appears set to become new manager Manuel Pellegrini s fourth signing for the Hammers following the arrivals Issa Diop, Lukasz Fabianski and Ryan Fredericks.
The board thanks [Balbuena for] the services provided and wishes him luck in his new journey, a Corinthians statement read.
West Ham are due to visit Swiss side Winterthur in their first pre-season friendly on Sunday.
