I was in the pub on Saturday watching Arse v Scum and of the 20 or so in "my crowd" about 15 of them were United fans. At half time, during a bit of Liverpool/United "banter" I confirmed that United were the 2nd most successful British team ever.
The heated argument that ensued was great fun. No mater how many times they told me (and 2 other LFC fans with me) that they had won more league titles and more overall trophies I, very patronisingly, congratulated them on winning a few more Charity Shields and World Club Championships than us but that nobody in Europe will take them seriously because they've won the CL about the same amount of times as Nottm Forest and Porto. I finished with "The big teams like Bayern, Liverpool, AC Milan, Barca and Madrid have all won it 5 or more times and if we win it this year we'll have won the most prestigious club trophy twice as often as you guys so how the fuck are you more successful than us"
I'm nearly 55 and I STILL love those angry pub exchanges between rival fans 🙂 and in fairness once the game was over we are all best mates again.
