Okay, so: Ratcliffe and Qatar both make offers. Ratcliffe's offer is flexible (meaning that he is willing to buy all the Glazers out, but if the 2 bastards are adamant on staying, then he will take a 50.1% controlling stake and later buy the rest), but Al Thani and his guys want the 69% and later probably the remaining 31%, so I assume they'd want to take United private.
Both offers will have a / share valuation.
Let's say Ratcliffe's is 1.20/share, and Qatar's is 1.10/share.
This means that the Glazers would receive altogether more money right now from Qatar, since they would be paying for all 6 siblings' shares. However, if they go with Ratcliffe, the 4 siblings will get more money right now due to Ineos' higher valuation / share, but Joel and Avram will also receive more money in a few years' time. That's why I don't understand why this is even a question.
