Former Arsenal manager George Graham believes that Diego Costa’s behaviour in Chelsea’s match against the Gunners at Stamford Bridge will make him public enemy number one – and rightfully so.

Speaking on BBC Radio Five Live Sportweek, the former boss compared the striker to Didier Drogba, saying that although the latter was strong and wasn’t afraid to throw his weight around, he never overstepped the mark.

“I think [Costa] is going to be targeted man now by the officials and probably rightly so,” said Graham.

“Drogba was the main man for nearly 10 years and he was very, very physical but he didn’t take to the extremes that Costa has taken it to.

Graham went on to say that he believes Costa should face punishment for his actions and that he probably will.

“Although you’ve got to keep that physical intensity, once you step over the mark he’s got to be dealt with by officials, it’s as simple as that – and I think he will be,” he said.

Costa was lucky to stay on the pitch after grappling with Laurent Koscielny’s face, hitting him, and then pushing him to the ground with his chest. The situation then got even more heated as Gabriel steamed in to defend his partner, which eventually resulted in him kicking out at Costa and getting red carded.

If Graham’s wrong and the Spain international doesn’t face any punishment, huge questions have to be asked about his apparent immunity in the Premier League.
