Leeds are a big club, no denying that but the fans and sections of the media are deluded putting Leeds in with some of those clubs, notably ourselves.
Anyone can pick and choose brief periods in history where their team has done well but in overall terms and recently, Leeds are no where near a few of the the clubs mentioned in that list.
Leeds had a great period 50 years ago and did well around 20-30 years ago. What Leeds fans need to be able to explain if they regard themselves so highly is why they are so far behind a club like Everton in most of the obvious "big club" measures yet still claim to be similar sized or even bigger. Titles, overall trophies, seasons in the top flight, home crowds, highest average attendance, highest record attendance, seasons in the PL, wealth. For a City their size and being the only club, the home crowds are poor. The away support is admittedly excellent, one of the best in the country for turnouts along with ourselves.
Leeds have the edge in Europe, but then we were banned at our height. If Leeds were banned late 60's/70's like we were 85-90 they wouldn't have the record they had.
That said, both of us are also rans at best at the moment. Neither of us currently come close to the modern day Man City or Chelsea unfortunately.
