That injection was THE most blatant FFP dodge, you almost have to stand back and applaud it. £30m for first refusal on naming rights (wtf?), and just the amount needed to balance the accounts. Amazing. lol ???
But it seems likely to me that'll be followed up on. So yeah, from the outside looking in, I feel like you're being too pessimistic.
A decent sized naming rights deal from USM with the stadium funded in the traditional way seems to be the way things are going. The stadium is happening, you'll get a decent naming rights deal from your owner's mate, but you'll still have sizeable, but manageable, debt as well.
(on the other side of the coin - the posts about Usmanov funding the whole thing seem to be from the same line of thought that had him personally piloting a ship up the Mersey with a load of free steel from Russia )
