Sorry mate, but that bolded is simply not fully true. Yes revenues were rising but that didn't impact the clubs valuation or Levy wealth, what he did with the club commercially did that more so. Building the stadium, having the foresight to make it into a commercial powerhouse, making the NFL deal. It was his foresight and hard work over 20 years that made the quantum leap for the club financially and yeh it was aided by the PL money etc all, but it was never covering what was needed before the stadium to push on.
The footballing decision declined, but he was never as bad as people made out, yes he lucked out with some, but before the stadium or ability to flip players for major profits and go again, running at Net Zero and still have the club operating in Europe more years than not, that doesn't come from being crap on the footballing side. Where those wheels came off was when the operational side became to big, thats not not recognising flaws thats taking the eye off the ball and making some bad decisions (there isn't an owner/chair base that hasn't).
Overall, Levy had flaws, like I say, all in football do, from players to owners, but we are a much better club than before he took over, he undoubtedly raised expectations in our support base, just look at these pages to see that and he undoubtedly future proofed the club on the commercial side that will have a lasting impact for the good moving forward.
