"I think they have played into our hands and that the title race now is going to be between ourselves and Liverpool," Ferguson told United Review.
"I was shocked that Chelsea should part so soon with a manager of such great experience and proven success as 'Phil' Scolari.
"Their haste is a reflection of the sad way the game is going, with everyone from owners, the board members, the supporters and the media demanding instant success and showing absolutely no patience in the pursuit of their ambition."
"I would have thought it self-evident that winning prizes comes with stability and long-term planning," said Ferguson.
"Yet so often, when a club is faced with a few problems, wisdom flies out of the window in the hope that a new man can bring about a quick fix.
"Chelsea have called in a very experienced manager in Guus Hiddink and I am sure he will make an impact.
"At the same time, he has to start from scratch, perhaps putting together his own staff and gathering round him players of his choice which may take him some time."
