Yeah I think I'd be more concerned about how Swansea scored after a blatant foul. Kicked him the back of the legs twice, never won the ball, is one on one now and scores. Courtois is rightly booked and a penalty given, Fabianski cuts off Costa in a blatant check at the other end and nothing. The idea of big club favoritism is disappearing quickly.
Also Mark Hughes was sent to the stands because he couldn't keep his gob shut, completely unrelated and in no way a similar offence. You were just looking for another reason to throw a Chelsea dig which is a common occurrence, you're fooling no one. If you're that worried you'd have pointed out the above.
Who's this chap over the line?
