What SHOULD have happened.
Celtic: "You're getting the mandatory 5%, we want the Darwen End."
Rovers: "We will need 5-6000 tickets for the first leg. If we're only getting 5% you get 5% ie 1500 for Ewood."
Celtic: "1500 for Ewood is no good for us, tell you what if you give us the Darwen End we'll give you 3k with an option for another 3k."
Everyone happy.
Instead Celtic have given us NOTHING for the first leg, only what they HAD to give us and we've given them FIVE TIMES what we had to for the second.
Rovers have misjudged the first leg arrangements extremely badly.
