if we are talking "of all time" then there are a few.
when i was young the hatred wasn't there, they were just a normal club. their players were proper players, dunne, stiles johnny ashton etc along with law best and charlton were respected players from reds and blues alike. the same applied with our players to them.they didn't even milk the crash as they do now although its fair to say they dropped kicked the victims to a degree.
it all changed when edwards junior and fergiescum took over, they changed to the hated beast it is today, not just by blues but the entire football world, they are not called the scum for nothing.they wouldn't know fairness,sportsmanship or humility if it smacked them in the face.
i can't put on here what i feel about them fully as i would be banned but its safe to say that if i had 550 billion burning a hole that crass set of wankers wouldn't even exist.
as for the present crop there is only one least hated, in fact i like the lad.
paul scholes.put every aspect of the game on a list and this lad has it, a brilliant player, a worker, off the field a gentleman.
best prem player ever for me.
