Fer barged into Cahill, so Swansea shouldn’t have had their second. On the other hand...Courtois deserved a red for a two footed studs up challenge nowhere near the ball. A Chelsea defender deserved red for hauling down a player as the last defender. Swansea should have had another pen late when one of their players was hauled down by the arm in the box while he had the ball. Chelsea deserved about a dozen yellows for simulation. Costa should have gotten at least three or four on his own. He also deserved a yellow for deliberate head to head contact. He should have gotten another yellow or three for instigating.
I don’t understand why any official would let Chelsea in general, and Costa in particular, make a mockery of the game. I was planning to watch a football game and was presented with some kind of weird psychodrama instead. As badly written as the rules are, an official doing his job properly would have used them to stop this from happening. One call I’d love to see is a yellow for simulation after a player spends a minute writhing on the ground, then comes back into the game almost instantly at 100%, as Costa did at one point. Are officials spineless, stupid or crooked?, I wonder.
