Fun read. lol
OK, I'll say this as a Spurs fan. The Emirates isn't the best stadium in the world, there are things they definitely could've done better (some of which were beyond the club's control to be fair), but my God it gets a worse rap than it deserves. It's not the cause of their problems, and it's not like the library was famous for atmosphere before it. There's so much strawmanning going on here. If a stadium isn't an instant magic fix for everything (who said it was going to be?!) then it's not worth doing apparently. And there seems to be this romanticised view about what Arse**l would be now if they'd stayed put, as if the invincible team would've carried on forever. IMO they'd be playing in the library, with moaning fans, and Cheslea and City cleaning up. And they'd all be calling for a new stadium to close the gap.
So...new stadium which definitely helps close the gap, gets 14,000 more fans each game, amazing new location vs some romanticised timeline where everything suddenly improves at Goodison. Sorry, but it's a no brainer if the club can pull it off.
