We have zero knowledge of where that 25% goes. Could go to The Glazers, could be split between Glazers and minority shareholders and it could be all going to minority shareholders, so lets not assume anything.
Also, tell me why he would make only a 25% investment?
This sale process shows a) the Glazers dont want to full sale and b) there is a minute pool of potential buyers. Practically only Sovereign Wealth funds have the money.
So if you take a 25% stake in a business in the hope that you can flip that in the future, then you better be sure that someone will want to buy that stake. This process has showed how difficult it that actually is.
Of course it is. 70 year old man isn't investing to make a profit if and when a bigger fish comes in a buys the whole club for 10+bil. He wants to come in, take control and be lorded as the man who saved Man United.
If he wanted to make a profit, he would continue to do what has already made him the richest man in England.
