It was a clear and obvious mistake from the ref imo. Chelsea player stopped a clear chance of goal with his foul. Only time it is given a yellow now is when they give away a penalty kick.He wasn’t getting the ball but that doesn’t necessarily mean it’s not a red. I just think it would’ve been nice to see the ref stick to his guns having seen it in real time and given a yellow, was it a clear and obvious error from the ref? As soon as he’s referred to the screen he is subliminally told he should be changing his decision.
