Its ok as Arsenal think they still have lines of people waiting to get in the ground if people don't renew. I believe that this is a myth as the Emirates is now over 10 years, people have already seen the ground if thats the only reason for their visit, there are only so many tourist football fans as well. The prices at Arsenal are still ridiculous considering the little success they have had since this stadium, the ground has been pretty empty a lot this year in certain games.
Next season could really be a commercial disaster for Arsenal as they have never planned for finishing out of the top 4. Half of the fans might boycott buying the new shirts, renewing season tickets as the same problems will come again with clashes against Wenger and against other fans as the problem still remains for another 2 more years or further.
