A furious Cesar Azpilicueta was involved in an ugly confrontation with a Chelsea supporter following their shock 4-2 defeat at home to Arsenal.
The Spain international endured mixed fortunes at Stamford Bridge, scoring the Blues' second to draw the game level at 2-2 before conceding a stoppage-time penalty which Bukayo Saka converted.
And after referee Jon Moss blew the full-time whistle, the 32-year-old defender appeared to clash with a home fan and seemed to take umbrage at something he had said.
Initially, Azpilicueta put his arms out as the fan made gestures in his direction, seeming to imply Chelsea should have shown more fight.
