Maybe my maths is slightly out...
If we work off 32,000 as being the maximum permitted capacity, of which 4,000 is located in both tier of the Lep then that would be 28,000 home fans.
You would need a minimum away following of 2,000 with all home stands sold out to achieve a 30,000 crowd.
Even if every single home seat including restricted view was sold for next Wednesday I don't think we'll see a 30,000 crowd
