I don't normally buy into the theory that refs are biased against City, as it smacks of paranoia and a lot of the time simply isn't true. Regardless of who the ref is, there will be a thread on here pre-game saying we're fucked as a result.
However, I was apprehensive when Walton was announced as ref. The couple of times he reffed us last season he was shockingly biased, and the first half today continued in the same vein. Every 50/50 went in their favour, and he refused to give us a blatant corner and also a free kick when Balotelli was crudely hacked down from behind.
He even had the audacity, as the teams were coming off, to confusedly point to himself as the City fans booed him off the pitch, as if to ask "What, me?!".
Having said that, second half he definitely changed his approach and gave us more decisions than he had first half. Still the worse ref in the league though, in my eyes at least.
