So even though David Moyes has struggled to bring in the reinforcements he feels are necessary for his own squad, Mourinho needs to do more as he has so much ground to make up.
Yet the bookmakers have still installed Chelsea as championship favourites, a situation whose only rational explanation can come through the force of Mourinho's personality.
Ferdinand can hardly ignore it. But he has been around for long enough to know charisma itself cannot secure silverware.
"The fact they have a new manager adds a new dynamic to the game," said Ferdinand.
"Mourinho obviously has a big personality. He has been there before so he knows the league.
"He is newsworthy. It makes good reading for the public with him around.
"Whether it helps them get closer to where we were last year remains to be seen. It will certainly have no bearing on the way we approach the game."
