What utter shite, and absolute paranoia. If SISU, as you say, don't give a toss about the fans, why would they go to the effort of planting people on this forum? They couldn't give a flying fuck what is said on here.
My stance is that whilst I don't support SISU (they have made many poor decisions, are partially to blame for the relegation and their communication with the fans is pitiful), I do believe that ACL are as much to blame for the current situation as SISU. The club have never been able to afford such high rent, ACL have known this for the past 8 years, and yet they have never offered to restructure the deal to help the club achieve a manageable method of rent payment ensuring the club's sustainability and future. SISU inherited a mess, and have funded that mess for years.
ACL and SISU have had messy negotiations and now there is no deal to be done. There are two sides to a negotiation (a negotiation which we fans don't actually know a great deal about). I can guarantee it was never part of the SISU plan to organise a ground-share with Northampton.
