feck me you lot are optimistic, aren't you?
I think Liverpool might well nick this (based mainly on spirit, you only need to look at this board sometimes and the 'we're gonna get hammered' mentality to get a picture of the overall feeling around the club) but those who think you'll lose 5-0, when has this ever happened? United aren't gonna lose 5-0 to anybody in this league, regardless of how mediocre they're playing.
Liverpool are pretty good, but not that good. Realistically, they are a team who without the ball lack talent and hide behind a system, albeit it's a good one but they fade late and if you can work around it and hit them quick on the counter and get at their back 4 they are vulnerable. Attacking wise they have some dangerous players combining pace (Mane) and a couple of goalscoring attacking mid's (Coutinho, Firmino) but their midfield distribution is basic.
If United are up for this, they can quite easily come away with a point or better.
