you are thinking short term. For me its about the long term status of the club all the top clubs in Europe have magnificent stadia Anfield is landlocked even buying up the terraced houses over past decades. It's also in an area of Liverpool where nothing is happening.
I guess it all depends how you view the club and your time horizons. If we built a new stadium tomorrow at my age I would not see the benefit (in fact it would be worse for me) however fans in 40 years time might.
If that does not bother you then yes lets live for today
As you say, fans in 40 years might...I am not sure to understand how a beautiful stadium will attack fans, I rather think it is trophies and quality of football/players which attract fans. Newcastle for years had one of the highest stadiums, Arsenal for years had the newest stadium, not sure what that has done to get new fans. You are not convincing at all
You don't understand the point the stadium is a long-term thing and represents the status of the club this is reflected in fans and exposure long term. Look at all the top clubs in the world they all have magnificent stadiums. Liverpool is the exception and sooner or later it will catch us out. Re Arsenal you are confusing short term success on the field with long term development. Managers and success comes and goes over time.
Yes, I probably dont understand how the design of a stadium will have much of an effect on a club. Yes I can understand when it is the seating capacity and the pitch quality, but how nice looking it is, really? Qatar will probably have the best looking stadiums soon, are they going to takeover world football in the long term? Dont think so. Wembley is one of the greatest stadiums in the world, does that get England more fans?
Anfield is held in huge esteem globally as well, everyone knows the stadium, it is part of the team/club, opposing managers talk of how they fear it and the atmosphere generated, look at games like Barca in the CL, that was amazing, most new stadiums have struggled with atmosphere, so we would probably lose that advantage.
As long as the ground is invested/improved, like it is now with the Main Stand and new facilities there, and the proposed Anfield Rd improvements, I do not see a problem staying at Anfield and improving the ground, which will have the same capacity as a new stadium?
