Jose Mourinho defends Diego Costa

Chelsea boss Jose Mourinho has admitted that he did not see anything wrong in Diego Costa's behaviour during the club's 2-0 win over Arsenal at Stamford Bridge.

The Spain international played a major role in the sending off of Arsenal defender Gabriel Paulista in the first-half, and this changed the complexion of the London derby.

Mourinho has now backed his star man by insisting that he gave a 'man of the match' performance, and saw nothing controversial in his side's convincing win over the Gunners.

"If you want to speak about Diego Costa with me, it is just to say he played how he has to play and that's why you have full stadiums and you sell televisions around the world for millions and millions because the game has to be played like that," he told Sky Sports News.

Arsenal played the final minutes of the game with nine men, after Santi Cazorla received a second yellow card for a rash tackle on Cesc Fabregas.
