Your wording there is exactly how the club should have approached this, instead they did the complete opposite.
Sisu have blamed ACL for an agreement the club willingly signed, at no point have they accepted that the club (through successive owners) have put themselves in this position.
Sisu have played hardball tactics, trying to destroy ACL, then discrediting the entire company. CCFC have no legal right to anything of ACL yet they act as though they have the law on their side.
They change their argument like the wind. Up until 6 months ago only £170k rent was acceptable, then all of a sudden income streams were what they really wanted. They have a proven track record of poor business decision making, and have no credible plan going forwards, yet critise ACL as being poorly run.
If Sisu had acknowledged the club is where it is because of its own decisions, if they hadn't tried to destroy ACL and then critise its business plan, and if they accepted that they have absolutely no legal right to anything at the ground, and , most importantly, if they just come out and said 'Sorry, we have screwed up, we know its not your fault, but please help us ACL', along with a clear business plan of what reduced rent and some income streams would mean for the club, then it would be different.
If they had've approached it in this way then I would probably be supporting them, but unfortunately their pig headed arrogance has got in the way.
