This was the Red Devils' first win at Stamford Bridge in a decade.
Torres was shown a second yellow card for diving in United's highly contentious 3-2 win but replays showed he had actually been fouled by Jonny Evans.
And Ferguson rubbed salt into the wound by claiming the striker only had himself to blame and declaring he himself would have stayed on his feet and scored had he still been a player.
"Well, did he intend to dive?" Ferguson said.
"Jonny may have just caught him a little bit but you can either carry on running, which he could've done... But he chose to go down.
"He could've carried on and scored. That's what I can't understand."
The United boss added: "I would've never missed that chance. I would've taken it in my time. I would've never gone down.
"But he did go down - that's the issue - and he's already been booked.
"So it's his own fault."
Ferguson did, however, admit the visitors were fortunate with the winning goal scored by substitute Javier Hernandez from an offside position after Chelsea had been reduced to nine men.
"They say that the winning goal came from an offside, so that's the bit of luck I think we got," he said.
"I said before the game we've had some shocking decisions down here.
"It's very difficult to come here and get all the decisions - I must say that. It's very difficult."
The United boss even took issue with Antonio Valencia's own booking for diving under pressure from John Obi Mikel.
He added: "I thought that it got a bit nasty. The booking of Antonio, I can't quite understand, because he's right through. There's no reason for him to go down.
"He was definitely taken, and he's been booked for it, because it was Mikel, you see, and Mikel's already been booked.
"I think that's the reason the referee had to do that because he would've had to send Mikel off."
