For somebody who couldn’t see the arm across Fernandes, the referee seemed pretty certain it wasn’t a foul. Take a look at his theatrical reaction to the claim. If he didn’t see it he couldn’t be so certain there was no foul. If he did see it then he must have thought it was not enough to give a foul and send the bloke off. He got it badly wrong. Then there’s the assistant. What’s the point of him if he won’t assist the referee in making the right the call.
