Solskjaer's United have not lost in the Premier League since that trip to Merseyside, winning eight of the next nine matches ahead of Sunday's showdown. Yes, Liveprool have been on their way up, and United on their way down ever since Sir Alex Ferguson left, but this season Man United see themselves being overtaken by not just one, but both of their most hated rivals.
"I think you have got to look at the rivalry", said Rob Mager, a supporter for 30 years and the designer for the club fanzine "United We Stand".

And surprise surprise, they've already started blaming the ref. Mancs seem to imagine that Oliver will be waving penalties around willy nilly - but Manchester United definitely seem to have a worse record when they get Oliver. That's the same every year but this feels even bigger because Liverpool are going for the title with City. I will not explain to everyone why they don't start because they will all start games.
"So today, seeing United, I am so happy".
