Santos striker Sebastian Pinto has sparked a row between West Ham boss Alan Curbishley and football chief Gianluca Nani.
The Mirror says the Chile international is expected to play in a closed-door game after being told he was signing on loan with a view to a four-year deal.
Nani, whose job includes finding new talent, persuaded the Brazilian club to loan out Pinto and talked the player into the move too.
But Curbishley refused to play Pinto in the "trial" match.
