This is the problem with your argument, it's not to make us United, Real or Barca, it's to make sure we are in a better financial place than we were before. The argument cannot be that the new ground will suddenly make us bigger than well established super clubs, that isn't happening. The financial argument is that it makes the club stronger and more likely to remain as a Premier League club, more likely to retain players and harder to extract players away from than we already are. You can't expect to make us the world's biggest sporting franchise, to expect that is delusional. Be careful here my argument is not that the new stadium will allow us to buy players for £200m that's not happening because that kind of money comes from an Oil Well or state aid.
That is an opinion, it's not one that is entirely proven, how a team finds and retains their players is not predicated entirely on money. You can see this by the squad we currently have, they have not cost us necessarily high transfer fees and they are not the best paid players in the league, yet here we are. Not every player is soley motivated by money and we have advantages beyond just the money, we have a respected manager, we have a base in London (which is attractive to most non english players), we have a bonus structure. Our players aren't pleading poverty and it is inevitable that we will not keep all our talent but we'll also buy well and develop our players, those players in our development squad will see that if they're good enough they will play, unlike some of those languishing or being loaned out by Chelsea & City, it's not delusional to believe we can't retain more of our talent as time goes on. As for honours, do you think that's what attracted Aubemayang to the Emirates? Also we might lose Alderweireld, you know what? If we do, horrible as it will be to lose him, we'll replace him, that's life.
The qualification culture? Seriously! They have been 17 years, do you think we had a qualification culture in 2001? Were we winning things? Had we been pretty much shocking for the decade leading up to that point, barely qualifying for Europe, barely surviving in the Premier League? If someone spoke to you back then and said, 'this lot are going to give us a team that can challenge for the league, they're going to build a new training centre that looks world class, a new stadium and guess what, you're even going to finish above Woolwich.. Would you be arguing about a 'qualification culture'?? I don't get it..
The horrible truth is we may not win a thing and you have to ask yourself is it better that we've had a bloody good go at it with a quality squad or do we have to regard it as another failure? You say that Woolwich have won 3 FA Cups in 4 years, that isn't saving Wenger, do you not see? Once you win the FA Cup that will never be enough, you might say it's a nice problem to have, I am not so sure.
