If you look back, the deal apparently offered was similar to the rent being paid for the last couple of years at Highfield Road, so, a brand new stadium, with potential for 10,000 extra paying customers would not seem overly high. The issue starts when you then can't afford it anymore, which by default leads you to think it's "too high".
Of course, the fact when the deal was originally done, there was an option to base the rent on a league based deal, and the number of attendees as well, meant, with hindsight, the wrong deal was agreed perhaps?
CCFC should have sat down and looked to negotiate this from the outset, when SISU bought the club or when we dropped to league one. Or, they could have focused their attention on the ARVO "management Fees" as they do seem to be obscenely high.... Solve that and the rent isn't such a big issue.
Of course, we all know it's never been about the rent.
