Giggs says, however, he still has plenty to offer the team.
He told manutd.com: "I'm experienced enough to know I'm not going to start every game or even play every game. The thing I want to do is be effective and contribute to the team. As soon as I stop doing that, I'll finish. Hopefully I can just contribute to the team, to the club, whether it be starting a game or coming on and using my experience in games. You want to play every game, of course, but I know I can't."
