I don't think all that much has changed, if United really wanted one of our players they could get it done, all that's changed is the numbers, they can still afford to pay them twice what we can.
What has changed is that the cost for United would be truly, staggeringly prohibitive relative to what they'd get, *and* possessed of a 'Premier League markup' that would take an already steep price even higher just by dint of them being a domestic team.
Sure, if they wanted, they could throw 100-120,000,000 pounds at us and ask for Alli or Kane...but *just* one of them. They could afford to pay either much more than we could, but at that price *plus* the presumable necessity of offering them mega wages to get them to actually push for a move down to United, the cost of the deal as a whole becomes insane for what you're getting. You're looking at an investment of 175-200,000,000 pounds on *one* player, including the transfer fee, wages, bonuses, solidarity fees and agent payments. Then, on top of that attempt comes the subsequent rush of existing United players clamoring for renegotiated contracts and signing-on bonuses given that they've seen someone like Alli or Kane take up 175-200m of United's cash, all told.
Still think they could go for more than one or two of our top players before their megamoney Javanese condom sponsorships start running dry relative to the cost of raiding us?
That's what Jose's grumbling about, I think. Of the European leagues, I think every single one in the top ten would offer mind-bogglingly better value for money than what United would get by attempting to a hobble a rival like us - and, worst of all, that obscene price paid may not even achieve the objective of hobbling us anymore. Prising one player from a team like ours won't kill us off, it would take Bayern-esque pillaging similar to what they do to their rivals *every* season for a few years.
And that will assuredly take several hundreds of millions to achieve. To say nothing of trying to hobble anyone else in the top six - it's almost completely out of the question with Liverpool and City given the rivalry, and out of the question with Chelsea given Abramovich's continued funding of that hole. All of those clubs are 99.95% impossible for United to breach. The only other rival they could try to 'hobble' like us would be Arsenal, and they have a massive cash reserve and no reason to particularly need United's money (although they do have the habit of letting their top players run down their contracts, which isn't the case with us - so maybe they're more susceptible to that sort of thing).
Long story short, United could *maybe*, if they lost all sense and reason, try their hardest to blow hundreds of millions on *temporarily* hobbling us by taking one or two of our players...but that is now exceedingly hard to do. And they absolutely can't do it with *all* their rivals, or even anyone else bar Arsenal. So there's really next to no point spending untold millions temporarily hobbling one if the rest are all impenetrable. All that's down to the TV money..but also down to Levy, I think.
