i find it laughable but bloody annoying.
liverpools history is basically the success of the 60's, 70's and 80's. the hillsborough disaster in the 90's. and the miracle of instanbul in the 00's.
uniteds is their first european cup, the munich disaster, and their 13 premier leagues.
our history is basically being shit for 90 years, bringing a banana into a stadium, conceeding THAT ricky villa goal in the fa cup, getting relegated to the 3rd tier, being reformed in 2008, empty seats, and winning stuff from oil money and our owners are dictators who treat women like slaves.
i honestly think most fans only count history from the 1960's, anything prior to that never existed.
So the fact we won the fa cup before united and around 60 years before liverpool ever did is just a myth and didnt really happen.
