#Football shamed again by 'biting' scandal: Uproar as #Chelsea star #DiegoCosta appears to sink teeth into rival player in FA Cup clash

Volatile Chelsea striker Diego Costa appeared to bite a rival player in the team's FA Cup quarter final defeat to Everton tonight.
No stranger to controversy, the Spanish forward squared up to Everton's Gareth Barry who seemed to take him out with a rough tackle.
Both men were seen pushing their heads into one another before Costa, 27, who was already on a yellow card, sunk his teeth into Barry's neck.
