Whilst I agree that the state of refereeing in this country is the pits and they do genuinely seem to be very harsh on us, I don't think we should pin our lack of points on them. For instance we should have been 3 nil up at Wolves before the Luiz debacle.
We shouldn't have given away a soft goal at Villa early on, we created enough chances to get something out of the game.
We have been very wasteful in front of goal the past few games, that is more of an issue than the dodgy refereeing IMO.
