Edu Gaspar's future as head of global football with Nottingham Forest is in doubt.
The 47-year-old, who is expected to attend the London Stadium on Tuesday for the crunch game against West Ham, was appointed in July after leaving Arsenal.
It was hoped his experience and contacts would help Forest to build their brand on and off the pitch but, with the club facing a relegation battle, concern has been raised over signings.
Forest come up against their former boss Nuno Espírito Santo on Tuesday, and his departure from the City Ground at the start of the season was blamed in part to his poor relationship with Edu.
