This is very subjective of course and all a matter of opinion so remember nobody is right and nobody is wrong. Just put an argument up for who you think it is or agree with other people about theirs. I don't think it will surprise anyone when I say it's my club, Newcastle United. Before football really took hold in Europe, Newcastle were the dominant force in the world before the first World War, we won 3 league titles in 5 seasons, and reached 5 FA Cup Finals (which was considered equally as important to the league then) in 7 seasons. We were the best supported club then as well. We won our last League Championship in 1927, and our last FA Cup win in 1955 a decade, the third in four years, but since then it's been bleak. In 1969 we won the Fairs Cup/basically the UEFA Cup, but that's one trophy 51 years. We've been to numerous finals since, lost them all, we've came 2nd in the League, had 12 point leads, blew them, it's not difficult to understand why some people think the club is cursed. In terms of a true fan base, some might say this is contencious, Newcastle is probably second to Manchester United in England, certainly in terms of average gates, although in fairness, I believe Newcastle and Arsenal could easily get 70,000 if there was room, Liverpool couldn't. If you look at these facts.... Newcastle are the first and ONLY club in the world to average over 50,000 for top flight and 2nd grade football (56,283 Division Two 1947/8 and 53,839 in Division One 1948/49). - 1906/07 Newcastle were the first club in the world to average over 30,000 for league games - 33,235. - 1946/47 Newcastle were the first club in the world to attract over 1 million for league games. - 1947/48 Newcastle were the first club in the world (along with Arsenal and Man Utd) to average over 50,000 for league games - Newcastle 56,283; Arsenal 54,982; Man Utd 54,890. ...it's hard to argue with the fact that there can't be a more underachieving club than Newcastle United. Presently we're the 10th best supported club in Europe, in terms of average gates, and get one of the highest revenues as a result of this. Only Manchester United and Chelsea have spent more money than us in the last 12 years, and far far more than Arsenal, we've spent £52m in the last 16 months alone just on players (which is probably the most in the world over that period), yet still we're shit. It breaks my heart to say I don't believe we'll ever break this hoodoo, and when you look at smaller clubs in a lot of the above terms, winning Champions Leagues (Porto, PSV, BVB), and domestic championships (Blackburn, Chelsea), it's horrible. We've won 11 major trophies in our history, and clubs like Liverpool have won 50. Do you agree with my view point or can you put a compelling case for another club.
