My understanding is the investors own 80% of the club and James 20%(of that 80% Chien is the majority holder),Companies house shows the Council still own 50% the other 50% is not declared, but given Patrick resigned when the investors joined that would suggest either James or PC etc own the other 50%. I thought I read somewhere PC saying they were trying to negotiate with the council for the other half, which would suggest they own half the ground.
Most of the squad are on a relative pittance coming out of League One. I remember two examples after the 2015/16 promotion. One first teamer was on £900 per week and another £1,500 per week. The club can't afford much of an increase, so few are happy with the new contracts they are offered. The dissatisfied players are sold and replacements are brought in from lower in the pyramid who naturally accept what's on offer. These players are rarely job ready, so we return to the appropriate level for that sort of expenditure.
