4) Is Costa the ultimate wind-up merchant?
Chelsea striker Diego Costa is well known for his fiery temperament and the tendency to get underneath defender’s skin.
Arsenal’s Gabriel was the latest victim yesterday, being shown a straight red for kicking out at the Blues striker.
The Arsenal defender was reacting to Costa’s treatment of his team-mate Laurent Koscielny, who was shoved three times in face before being pushed to the ground.
Gabriel immediately confronted the Spain international and a lengthy argument culiminated in him lashing out with his foot.
The game was turned on its head following Gabriel’s sending off and the Gunners were unable to mount a serious fight back afterwards.
Santi Cazorla was also dismissed, being shown a second yellow for a foul on Cesc Fabregas.
The big question is: how did referee Mike Dean conclude Costa’s treatment of Koscielny was fair?
