Spurs under ENIC/Daniel Levy have been brilliantly developed in all aspects of the club. Absolutely no dispute on that at all, and you're now a sustainable member of the elite. One of the, if not the, best managed clubs of the recent era. I do think there's a variety of different issues to consider though: 1) Spurs from the mid-1990s to mid-2000s were drastically under-performing against their potential, you were effectively a sleeping giant due to poor management; 2) Spurs have long been a very big club with a storied history and a large fanbase; 3) Spurs were a key player in the ending of shared ticket revenue in the 1980s and the foundation of the Premier League in the 1990s, which were both driven by the greed (let's be honest) of the "big five" at the time, and were the first club to list on the stock exchange. What I'm trying to say is, Spurs are hardly a romantic rags to riches story. You're more a story of a big club now being managed well to meet (and exceed) your potential. I think we've had this discussion before, but when I said "mid table" clubs, I'm really meaning clubs in a far less advantageous position to the one Spurs were in.
It'll be interesting to see if anyone can follow Spurs' path in the future, maybe Everton, the only one of the old "big five" not currently in the elite club? Plenty of others with huge potential too like Newcastle, Wolves, Villa, even Leeds, etc. It'll take unbelievably good management for anyone to do it, and overcoming the one step forwards, two steps back challenges that Spurs suffered through when other clubs (United, Real, etc.) took your best players. Under our sugar daddy, City have benefited from good management too, but obviously the biggest thing is that the spending power allowed us to totally jump over that one step forwards, two steps back issue and hold on to all our players, while at the same time allowing us to make unlimited mistakes in the transfer market. Spurs have had to be close to perfect to achieve what you've done, and so will any other club that tries to follow your model. City (due to our sugar daddy) didn't need to be.
