The Serbia defender missed the Premier League champions' tour of the Far East and Australia due to a back complaint.
Vidic told MUTV: "I am pleased that I have 90 minutes under my belt. It's a long time since I've played a full game.
"I am pleased with that and I hope that after this game I can pick up my fitness and I will be ready for the beginning of the season.
"It's frustrating when you don't get the games. I've done some good training but it's different when you're playing a match.
"I got 90 minutes and we have two more games before the start of the league season. Hopefully I can get another 90 minutes before then."
