Yes I see your point also. The problem is that there are very few people who will spend the huge amount that the Glazers want from the sale.I get your point but we would directly be owned by the ruling Saudi family, the people who actually give the orders to commit these atrocities. Talk was that the Crown Prince himself would buy us, that's like Kim Jong Un owning us.
The outlay is huge for a single businessman, also as I've said previously I'm concerned that businessmen will be treating United as an investment (as have the Glazers.)
To truly kick on and compete with the top European sides we need this type of owner.
As mentioned already, I would like to think that this would go some way to marginally improving things over there, United has the most fans and a huge following, any negative press would be hugely detrimental for their public image from the start.
