no, its two guys who are in the abu dhabi investment group, but not everything they do is linked. They own things privately, and pool money together for joint ventures. If the joint venture group bought both clubs it would be an issue, but its simply two of the investors privately owning clubs, and working on other things together.
The only bad thing would be, with Pompie not desparate for the cash, they might hold on to Johnson, the bad part being we won't be able to laugh at Benitez for spunking 15mil on him.
The other thing being I've seen a quote that the first thing to sort out if it goes through, is getting existing players tied to new contracts as apparently many are up in the close season. Frankly Pompie need a clear out of a lot of overpaid crap, Kanu must be on silly money to barely ever play, Campbell makes mistake after mistake, ,one in that last game that was laughable, again on huge wages. I'd be letting a load of players go if there was new money for investing rather than signing on fee's for players to stay who should really be released/retiring.
