Video replay shows the former Atletico sticking his tooth in Barry’s neck after what was supposed to be a forehead confrontation between both men.
But according to a Chelsea spokesman at Goodison Prk as reported on the BBC, the Spaniard who regretted his action insists he did not bite the Englishman.
“Diego spoke to club officials and expressed regret over his reaction to the challenge from Barry that led to his red card.
“But Diego was also very clear that he did not bite him at any point during that altercation.” The Spokesperson said.
The striker’s booking for an early challenge on Barry was perhaps a bit harsh after the two players collided in a loose ball situation with Barry clutching his head as if he had been hit but there was little contact.
Costa argued with Everton players after the challenge before being booked. However, after he was shown the yellow card, Costa walked towards the referee and visibly spat on the floor right where referee Oliver who did not react as his attention appeared to be elsewhere was standing.
Costa was later sent off for a second yellow card after again clashing with Gareth Barry, whom he appeared to bite during a heated exchange.
