It was Vidic's first appearance since breaking down at West Brom for the start of the season.
"I have never been out so long," said the recently-retired former Serbia skipper.
"It was eight weeks and it was a difficult time.
"I was desperate to be there but at least we did well, so I didn't have that much pressure to come back and play.
"That helped me. Now I feel well. I don't feel any pain, which is the most important thing.
"I can move on, try to reach my top form game by game and help the team reach our goals."
