I'd love to know about the finer details of the original rent negotiation. PWKH has been on here and stated that the club turned down the offer of a sliding scale, as they thought they'd be back in the Prem soon and it wouldn't be worth while. He also said that until Sisu no-one seriously asked for a new deal. There's evidence Robinson went to ask but got nowhere but PWKH didn't class that was "whole hearted" so make of that what you will. Similarly, when Leonard Brody went to the papers saying the rent was killing the club Igwe and Delieu went public stating how it wasn't and that they are happy with it. So I find it a little hard to feel too sorry for the club here.
WRT how the council dropping the rent like they did. Well firstly, how you imagine things going when you first open and how things are going 7 years later are two different things. Circumstances changed significantly for both ACL and CCFC in that time. IIRC the original sliding scale had a level of roughly £400k/year in L1, maybe even less, I'm not sure. But as I say the original rent was too high and a negotiation was needed long ago.
The move from £400k to £150k was for two reasons: firstly the £400k offer included access to ACL's books for FFP reasons (and I think other revenue but am not 100% and some say it didn't). Secondly when the Sisu deal for ACL's mortgage fell through the restructured loan with CCC meant that the finances were better off and that ACL could offer a deal that isn't commercially viable but recognised the value the club has to the community/project as a whole.
At the end of the day, no matter what you think of them politically, the likes of Mutton and Lucas for CCC and the Higgs' ARE Coventry City fans. None of them want to see the club hurt. In fact that was Mutton's downfall as he stupidly thought he could engineer a situation where Sisu left the club and rightfully he fell on his sword.
I also find it slightly funny how you want nothing to do with the council because they didn't cut the rent fast enough, but will give a pass to Sisu who defended the rent figure and also moved the club out of the city. Like I say not judging, I just find it interesting that people on both sides will accept some behaviour and not others.
