@Cazza agreed on Utd, Jose's Chelsea and Fergy's Utd were worse.
As for the Arsenal goal, the Ref has his hand up and is clearly playing advantage. Quite what advantage he thinks Liverpool will get from a loose ball bouncing about in their box when it's full of Arsenal players, is beyond me. But if you can find the zoomed out view of the incident, you can clearly see he puts his arm up a few seconds before he blows his whistle. And he blows his whistle before Arsenal score anyway.
That one was a non-story for me. The penalty is more debatable. I have definitely seen them given. Konate does get a bit of the ball, and as per Sanchez "getting the ball" last week before literally upending Curtis Jones, apparently that then negates you munching someone after. I still think it falls in to the "seen them given, seen them not given" category, but if I had to give odds on it being given, I'd probably expect to see it given more often than not given, say 60:40 ish.
As for Almerim. He was all set for Pool then decided to be a dick and go and meet with West Ham to discuss becoming their new manager. Unsurprisingly Pool told him exactly where he could **** off to. He seems to be very keen on 3 at the back, which will suit Harry Maguire (new contract incoming, watch and see). But his character would worry me. I'm not a fan of people who try and dictate to clubs, it always seems to end badly. Either way, it's all West Ham's fault for scoring that penalty! ;-)
