Leicester will never be an elite club. Neither will Atalanta, neither will Frankfurt, neither will Real Sociedad. If there's any threat of it, the goalposts would move again. Even if we managed to qualify for the CL 5 years running and then missed out in year 6, making us one of the wildcards, they would have the rules changed before it could be allowed to happen.
The only way we'd ever become an elite club is a Man City style takeover and even then we'd still be shunned for others who are already 'big'. It's just the way these people view the game. They have absolutely no feel for the game, have no appreciation for sporting achievement and can only see money. Such people will be furious that Leicester are likely to qualify for the Champions League again this season whilst one of Chelsea or Liverpool miss out. I'm not just saying that because I support Leicester, it's nothing to do with who we are, it's who we aren't, and we just happen to be the ones who put up the best fight, which I'm immensely proud of, but it always leads to a sad reminder of how soulless the sport is now.
