"Some" should read "all Lancastrians, Londoners and Merseysiders - and their entire Asian and Oceanic fanbases!"
Actually most "Lancastrians" hate Utd. That's the thing about Utd, geographically they have quite a small fan base of Salford and the surrounding area. Real Mancunians support City and Lancastians are divided up between Rovers, Burnley, the other Manchester-area clubs and then the scouse clubs.
And it should be a round of applause though I can't see any boos coming from West Brom fans. - no rivalry etc. Well, it's not like what will happen with George Best at the Liverpool v Man City game.
