The other four goblins want/wanted out and I guess this is the main reason the club got into the strategic review in addition to the need for funding options for the stadium. The need for the stadium is still there, we have wasted another half a billion on rubbish signings so there is still massive work to be done. I don't think the four goblins who want out have changed their minds and I suspect the 12 month clause has them in mind.
Those are the shares that will give SJR a pathway to majority control and I think Joel and Avram will still be with us for a fair bit. This also suits SJR because he never wanted full ownership and it will be cheaper to get control and invest in infrastructure rather than spend 6bn for total ownership and still find yourself laden with a crumbling, dated stadium when you can spend 4bn to get control and 1bn on the stadium.
I think the two goblins will force, from SJR, a concession where their shares will be sold for a higher price later on for them to agree to maintain their siblings' shares as class B after the said transaction. The Glazers, Joel and Avram in particular, preferred INEOS specifically because they weren't interested in a full buyout until they ran into minority shareholder resistence.
