Yes Utd won the league last season, but it's widely regarded as a poor year for the Premier League, with no team really playing amazing football. Utd were pretty much unchallenged throughout and finished what, 11 points clear?
That side hasn't aged or weathered well since then, and when put under strain of the spotlight of new management, and more competent challengers, it's crumbled. Could Fergie have kept it together? Possibly, but there's no guarantee.
What we know is that Moyes was chosen as the new manager and, with a side that was getting worse not better, he has improved on his Everton management record.
What was everyone expecting to happen?
There were other managers available last summer, managers with proven experience and pedigree. Moyes was the chosen one, and by the looks of that table he should be in line for another promotion.
