Arsenal midfielder Matteo Guendouzi taunted Brighton's players over his wage-packet during Sunday's defeat, it is claimed.
TV footage showed Guendouzi tussling with striker Neal Maupay after the final whistle of Arsenal's 2-1 defeat, a flashpoint that sparked a mass confrontation between the teams.
But the FA confirmed the 21-year-old French midfielder will not face a violent conduct charge because the incident, although missed by referee Martin Atkinson, was reviewed by VAR.
The Daily Mail says sources claim Guendouzi, who earns in the region of £40,000-a-week, spent the game taunting Brighton players about the financial disparity between the squads.
Arsenal's top earner Mesut Ozil earns £350,000-a-week while Brighton's wage ceiling is somewhere in the region of £50,000-a-week.
Maupay accused Arsenal players of arrogance following the win.
"He was saying the Brighton players were s*** and that he and his team-mates earn so much more than they ever will," a source said. "He's done it in other games as well. Arsenal are a decent club and hate that sort of behaviour."
