Clattenburg absolutely bottled it.
I'm willing to let him off, to varying degrees, with the various penalty decisions. For those I believe it was down to a combination of personal opinion, referee line of sight, and just being a bit shit at his job.
The Dzeko penalty was indeed a penalty for me, but he did make it look a little theatrical, and it's one of those strange ones which in real time looks more iffy than it does in slow-mo. Because Dzeko tried to hurdle the challenge the contact came far later than you would have thought, and therefore made Dzeko's tumble look really, really late.
The Skrtel penalty was absolutely a penalty, no-one could possibly deny that. The only possible explanation here is that Clattenburg, and his assistant, simply didn't see it. That's down to poor positioning, which in turn is down to just not being very good at the job. If Clattenburg sees it then I have no doubt he gives the penalty, he would have had no choice.
What I'm not willing to let him get away with, and where he certainly bottled it, is on the Suarez dive.
In not giving Liverpool a free kick Clattenburg has decided that Demichelis didn't foul Suarez, that's obvious. What's also obvious is that Demichelis didn't get a touch on the ball at all. So, if the defender doesn't play the ball, and doesn't commit a foul, then how exactly does Suarez end up on the floor in the way he did? The only possible explanation is that he dived. He didn't fall due to losing balance, he didn't trip, he intentionally went to ground. That's a dive, and that's a yellow card. There's no room for Clattenburg to use his discretion in the rules on this one, it's not a judgement call. A dive, or "simulation" if you like, occurs then a yellow card simply has to follow. The only reason Clattenburg doesn't give the yellow card here is because he knows he's already shown Suarez a yellow card in the first half. He knows he'd need to send Suarez off, and he knows that the media storm afterwards would be apoplectic. He's sure Suarez dived, but what if, just what if, he's mistaken? What if there was indeed a foul, and he's missed it? If he sends Suarez off it's likely to affect the result, and ultimately the title, what if he's wrong? A strong referee backs his judgement and does what he believes is right, a strong referee sends off Suarez. Clattenburg isn't a strong referee. He's a shithouse. He's panicked. He's scared. He's bottled it. He should have sent him off, as Demichelis didn't touch him. Hansen's pathetic attempts to claim otherwise on MOTD2 last night were just the ramblings of a biased man and were, frankly, an embarrassment to the BBC and to MOTD.
