Sir Alex Ferguson's men took the lead in the seventh minute through a Paul Scholes header, the champions then took their foot off the gas somewhat and allowed Grant Holt to pull the hosts level later in the game.
The Red Devils were saved by the man who has become a Manchurian, as he finished off a move in injury time to steal all three points.
The midfielder has now made 900 appearances for United, more than any player for any club, and the 38-year-old is still enjoying the game as well as already looking forward to next season.
He told MUTV: "To play 900 games for Manchester United is obviously something to be proud of.
"Especially growing up as a United fan.
"When you start off, you just set yourself little goals - to get into the team and obviously to stay in the team. Then you get a little bit greedy and want to win things, and then win more things. I don't think you ever envisage you're going to play that many games.
"I'm enjoying my football more than ever. The club want me to carry on so I want to carry on. I'm hungry and still want to play. I look forward to next season - hopefully after winning something this season."
The former Welsh international also used Scholes, who recently came out of retirement to make a return to Ferguson's side, as an example of why he is not ready to stop playing just yet.
"Seeing how much Scholesy missed it and seeing him now enjoying training and games, and playing so well, that is something I've got to think of as well," he added.
