Hang on, I'm apparently the one with selective memory, but you're the one that can recall every single little foul by West Brom yet fail to mention a single one from us that equally went unpunished.
As i said, if you seriously think the likes of Mcauley or any of their other defenders deserved a booking for persistent fouling then so did Mangala for us who committed just as many if not more little niggling fouls and got away with it. He consistently let little fouls slide for both sides,and as long as he's consistent in it, that's fine. Not sure what Yacob's challenge has to do with any other tackle or booking, everything should be dealt with independently, Yacob was rightly booked for his challenge, I do actually think he got the Delph booking wrong, i don't even think it was a foul but in real time it's fairly understandable for him to see it as a foul, it looked like one until the replays and in that situation where he saw it as a foul a card would be warranted. To not book him would be getting it wrong twice.
So this "horrendous performance" as you put it, currently consists of a handful of niggling fouls from them that didn't mount up to a possible card, a missed pull on Sterling, a debatable card for Delph and what else? There was nothing standout bad, nothing as incompetent as the decision to send Walker off against Everton. You can fume all you want but remove the emotion of Gundogan getting injured (something the ref had zero influence on) and nobody even mentions the ref tonight.
As for the personal insults, completely unnecessary and very rag-like.
