Incidently Liverpool didn't time waste, feign injury and take the piss out of the ref. Which is why no one was berating him for being week and a complete mug.
Is it that difficult to comprehend?
Perhaps he recognises he's being played and makes a point of making the player wait on the sidelines for a good few minutes. Not waive him straight on to sprint up the pitch immediately.
Letting them waste time feign injury to stop attacks, dives to win free kicks and allowing March to get kicked and playing on. Nothing wrong I guess, just shit pl refereeing standard
