As a long time lurcher (from the other side) on here thought I'd reply to this one, and I'm sure will be labelled as a SISU lover but...
I don't think ACL have strictly done anything wrong at all. But at the same time I don't believe they've ever had the clubs best interests at heart. ACL did everything they could to maximise their profits from hosting the football club at their stadium. The high rent, selling off the catering, car park charges that at most football clubs would be chastised for, selling corporate packages back to the club for a profit. All of these things were great for ACL, but simply not good for the club. And when a company is run like that, it means that the club are missing out on vital finances to fund themselves and to build a competitive squad. When there are no income streams for the club, playing at the Ricoh becomes very undesirable. And if you're ACL offering this to the club, then the club is bound to look elsewhere to play their games. So what ACL did wrong, from the clubs point of view, was to make playing at the Ricoh an extremely undesirable option. Even of you then offer better terms, why would the club want to continue a relationship with their landlords who have profited so greatly from their tenancy? You could say because of the fans, but I just think it says more about how SISU view their relationship with ACL. Doesn't make it right, and it's the fans who suffer, but it doesn't surprise me that SISU have taken the stance they have.
