Diego Costa was on the warpath again today during Chelsea's FA Cup quarter-final showdown against Everton at Goodison Park.
The Blues' season hinges on the game against the Toffees today following their Champions League exit against Paris Saint-Germain and their woeful Premier League form.
With that in mind, the FA Cup represents Chelsea's last opportunity for silverware this season, and it certainly seems as though Costa was pumped up this evening as he tries to help his side progress to Wembley.
It may be goalless on Merseyside at half-time, but that doesn't mean the game has been without incident, and Costa was of course at the heart of the action.
Indeed he may be facing a retrospective ban after the TV cameras seemingly picked up the Spanish international spitting at the feet of referee Michael Oliver.
The incident occurred after Costa picked up a booking for his part in a tussle with midfielder Gareth Barry. The former Atletico Madrid striker seemed to elbow Barry having battled with the former Manchester City man earlier on in the game.
Referee Oliver decided a yellow card was a severe enough punishment for Costa, who looked frustrated as he spat at the feet of the official.
Former Arsenal defender-turned-pundit Martin Keown said of the incident: "This is the infuriating side of Diego Costa. He seems to have to wind himself up to be a nuisance. He loves to play on the edge at all times."
Although it's been a difficult season for Costa, his form has picked up of late under interim boss Guus Hiddink. Before today's showdown against Everton, the 27-year-old has 11 goals in his last 15 games across all competitions.
