How do you consult with the fans ? Email, open forum at the ground ? all you will get is 1,000+ different opinions - just look at this forum as an example. The club are damned if they do and damned if they don't.
You're not going to please everyone every time but imo the club has a responsibility to listen to supporters, and also to speak to supporters.
With something like this (and I don't really have an opinion on whether it's a good or bad thing at this point) I don't think it would be too hard to let the supporters know in advance what the changes will be and why they are being made.
Then encourage supporters to feedback their experiences with the new change. Pretty sure the club would review their procedures after every European away so why not take advantage of the opportunity to involve the support.
