Departing Malaga sports director Mario Husillos is on his way to West Ham.
New Hammers manager Manuel Pellegrini and Husillos forged a close relationship during their time working together at Malaga.
The Daily Mail says Pellegrini is understood to have recommended his old colleague to co-owner David Sullivan.
Husillos' role at Malaga has been under scrutiny following the Spanish club's relegation from La Liga.
If, as expected, the South American transfer fixer is appointed, will play a key role in the club's recruitment policy alongside Pellegrini.
