Calm down Costa!

Costa still has a bad temper!

Diego Costa has never been known for his mild manners but in recent games he seemed to have found a way to keep his anger in check.

Well that was until a sliding tackle by Sunderland’s John O’Shea provoked what can only be called a massive over reaction and definite violent conduct.

The prolific striker, who has scored eleven league goals, was so upset by the incident that he angrily kicked out at the defender.

Costa only picked up a yellow card after his second aggressive act of the match where he caught Wes Brown full in the face with his trailing arm. As it is his 5th yellow of the season he will miss Chelsea’s next game against Tottenham.
