Totally Agree, I went to every cup match last season home and away plus replays and could not get a cup final ticket, although all our home games were poorly supported, I recall Leicester and Notts County, where the chant was "your grounds too big for you" due to stay away fans!! now I am going to the Charity sheild, taking my Son and daughter, who also went to every cup match and nephew plus another adult for a great day out and big match experience.
To be honest at this time of the year the financial commitments are pretty heavy, most people going on holiday etc, and it is no different for me, but £100 for 5 tickets isnt too bad albeit the delivery charge/booking fee is terrible!!
I think it is the travelling which is more of a burden (£135.00 for all of us) so why didnt we have the game near home say Villa Park, it is nearer for us, and also for MU as their fans would only have to travel the same distance from London, and Birmingham Airport is just as accessible for Foreign travel as Manchester!!!
