Well that was a confusing performance from Arsenal’s favourite referee.

Refusing, early on, to book Branislav Ivanovich for his first or even second yellow-card challenge, he waited until the 72nd minute before producing a card for the Chelsea man.

On the other hand, he didn’t give a penalty when David Ospina killed Oscar, so, you know, swings and roundabouts and all that.

That being said, we often see a keeper clatter a forward without getting the ball and nothing is given, so I’m not overly sure why it’s such a big deal this time around, although had it been the other way around I’d still be crying about it.

There is plenty that we could complain about on both sides but I think, if we look at it with a neutral eye, Oliver simply had a terrible game.

He missed Alexis Sanchez being trailed to the ground by the neck (thanks Ramires), Nacho Monreal being taken out of the ball and a host of niggly fouls that Chelsea like to give out but cry about when they are on the receiving end.

Chelsea, it seems, don’t like it up ’em.

I don’t overly feel like being fair, because it’s much more fun to rant like a loon but, as I mentioned, there are complaints on both sides and both sides can feel equally disappointed with another poor refereeing display.
