To a degree, as poor as it is, I can sort of understand it though. Paying fans, a lot of them possibly made their way to Merseyside last weekend, they thought they were watching their team bag a huge 3 points, only for a simply retarded challenge (I'd be disappointed if a Sunday league player clumsily lunged in like that) from the big clumsy Belgian.
There's not much difference in them booing or me or you saying "sit the f**k down Fellaini" on our computer screens, if I was at the game today, after his antics last weekend, I wouldn't want to see that Afro warming up either, in such a huge game when the scoreline is just 1-0.
If we miss out on the top 4 by a couple of points, a lot of people would look back at that single brain-dead moment. It'll be last weeks news soon, and he will be applauded before the season's out, it's just all the frustration and anger is fresh on the memory, on top of all the nervousness in the air today.
