Or not, Gary Neville refers to David Moyes as "a passenger on the ship coming through" and "United will change him" in terms of tactics. United's style of play is determined by what has gone before, which can been seen by the number of wingers in the current playing staff. Neville along with Jamie Carragher look at the potential scope for change, but there isn't much. The set up of the midfield two and the positioning of the support striker are the only real areas for possible tinkering. While he might like to employ a high press it hasn't been United's style and players like Robin Van Persie don't really relish chasing down lost causes, but there's always Danny Welbeck.
