Photos: Diego Costa bites Gareth Barry as he receives red card in Chelsea's loss

Diego Costa has hit the headlines again. This time, he was involved in a much bigger controversy during Chelsea's FA Cup loss to Everton on Saturday.

The Brazillian born Spanish forward was at the centre of the action throughout the match and was sent off in the final minutes after a scuffle with Gareth Barry.

The 29 year old forward, who had already been yellow carded, reacted to a foul by the Everton midfielder, jumping on his feet and pushing his head into his opponent's neck.

It is his first sending off since he joined Chelsea in 2014.

This could see Costa banned for a very long time.
