Chelsea manager Jose Mourinho believes Diego Costa was man-of-the-match in his side's 2-0 win over nine-man Arsenal at Stamford Bridge on Saturday.
The Blues striker was involved in a scuffle at the end of the first half, which saw Gunners defender Gabriel sent off, while Santi Cazorla received his marching orders late on.
However, while Costa's display was labelled 'unacceptable' by Arsene Wenger, Mourinho believes the Spaniard's performance was pure theatre.
"It's the basic thing of the game," he said after the game. "[Instead of Costa] I think you should speak about Gabriel Paulista. He's a good player who made a mistake.
"If you want to speak about Diego Costa with me, he played like he has to play. That's why you have full stadiums and the game watched around the world by millions and millions. The game has to be played like that.
"Costa was man-of-the-match for me. Of course [it was not a red card for Costa]. It was the same referee who made all the decisions in the game and who didn't give two clear penalties for us. There are also rules for what Gabriel did to Eden Hazard.
"Gabriel Paulista did something on Eden Hazard in the box that is allowed in rugby and not in football. In the box, it's a penalty. In the second half, someone did it on Diego Costa.
"In rugby it's fantastic but in football it's a penalty. I have to cope with my defeats, [Wenger] has to cope with his."
