The only certaintly is that 3 of our competition will be in a state of flux this summer
This is the key point i think, however if Mourinho goes back to Chelsea, I don't think they will take much time to re-adjust. UTD and Everton will though, and it's definitely a chance for us to at least catch up. All very dependent on what Arsenal do this summer as well, but if we can make some good signings, we could be in with a much more realistic chance of 3rd/4th.
Just being at a club for 10 years is an achievement in itself, but I don't see him doing
that well at UTD, even with an improved squad & resources. As someone else said- dominance over, but they're unlikely to 'fall apart'. Should even the playing field considerably.
