What a difference a fair ref makes though eh? Those saying it's never good blaming the ref, take note. He wasn't pro City, he just called it fairly, they still got all the niggly fouls but they are the home side.
He could have waved on the foul on Mahrez, he could have given Ramos that foul he asked for after backing into Jesus and falling over, he could have waved away the penalty, he could have booked Jesus for diving instead of sending Ramos off for the pullback. That's how it has gone in the past.
