West Bromwich Albion shirt sponsors Zoopla have reportedly threatened to end their multi-million pound deal with the club over Nicolas Anelka's 'quenelle' goal celebration.
Anelka made the gesture, which is said to have been an inverted Nazi salute, during the Baggies' 3-3 draw with West Ham United on December 28.
According to Marketing Week, the property website co-owned by Jewish businessman Alex Chesterman has told the club to drop the Frenchman for Monday's match against Everton or they will axe their sponsorship deal.
The firm are said to have delivered the ultimatum earlier this week, claiming that they do not want to be associated with the gesture.
The Football Association have stated that their investigation into the incident is still ongoing.
