Man Utd captain Vidic unsure how he'll handle another injury setback
He said: "It is not going to be nice if something happens again. Definitely you can have that in your mind but once you are on the pitch you just play and do not have time for that. I have worked hard with the physios, physically I have been strengthening the legs.
"It is obviously different playing from the start of the season.
"Now I am coming into December and the rest of my team-mates are on top of their games.
"I am having to come in. But I think I have worked hard and will manage that."
