This ‘rivalry’ all stems from Baconface’s comment about ‘knocking them off their perch’. He created this rivalry out of nothing and was probably more to do with insulting City than anything else. Looking back through history they have never really been rivals at all.
During Liverpool’s dominance throughout the 80’s their main rival for the title was always Everton. Since the start of the premiership the Rags had numerous rivals most notably Arsenal, Chelsea and more recently Us.
They have finished in the top 2 together on just 5 occasions, 46-47, 63-64, 79-80, 86-87 and 08-09 the last one you couldn’t call a title race at all. They have faced each other in the FA Cup final twice and twice in the League Cup Final (most recent of all these being 2003).
Hardly Barcelona v Real Madrid is it.
