This puts top four under serious threat now.
I don't see anyone scraping 4th like before, the top four in England will be made up of team that can mount a decent title challenge with no stragglers.
Arsenal need to recognize this and spend big as the threat isn't just failing to win the league, but missing out on their "4th place trophy".
In a way the whole Moyes thing could be the best thing that happened to united. Whoever comes in now get judged against that twat rather than Ferguson, making his job massively easier. Maybe that was the whole plan all along, flush out the cobwebs with a year of shit, then get back to basic.
