It's fair to say that David Moyes's start at Manchester United has been inauspicious at best.
At worst it's been very poor indeed, with the Red Devils taking a disappointing 11 points from their first eight Premier League matches, leaving them eighth in the table alongside Newcastle and promoted Hull City.
