Definitely not everyone.
A couple of (the right) signings would have been good, but there are several who have advocated for pragmatism since TFG took the reigns. See the season through, remain in the Premier League (almost accomplished) and invest in the summer when the squad needs the beginnings of a rebuild.
The summer, unimpeded by any international tournaments is the perfect time to bed new faces in and get prepped for August - assuming that we're able to do early business in June; or that we can strike up pre-contract agreements with impending free agents. Once June comes around, the PSR/FFP burden is lifted to an extent and we're in a new cycle; one that comes with a new stadium offering a HUGE increase in revenue and the additional bonus of sponsorship/naming rights which further boosts our capacity to spend.
I remain unconvinced that Moyes is the right man for this new cycle, but my word he's reinvigorated the place in the space of a few weeks.
