Sad times.
In regards to low attendance, what you guys have stated quite possibly is the cause; season ticket holders not attending coupled with high match day ticket prices.
To counter it they would need to lower ticket prices obviously but as for season ticket holders who don't attend... how on earth indeed do you put a stop to it? It may sound harsh but introducing penalties where by if they miss so many games in a row, or total, they could have their ticket suspended and let up for someone else to buy.
It will effect atmosphere but that could be because of the kind of people who go and attend matches?
I've often heard over the last few years here in the UK it being reported that the atmosphere at the Camp Nou is poor. A lot of people point the finger that there's too many tourists attending the games who merely "enjoy watching the game Barça play" or/and just want to see the superstars play i.e. Messi, Neymar, Iniesta, Xavi etc.
All being well, my wife & I are attending the game v Levante and I'm trying my hardest to make sure both of us have the chants drilled in & spot on. We're in 246, and praying we do have some fans around us that know the chants too who will get up and jump when necessary etc.
Having just checked too, it's the game marked down as the 15th Feb 2015, I know it's early but what are the chances the date changes? We'll be in Barcelona for Valentine's but starting to sweat if the date of the match is moved!
