The England winger joined United from Aston Villa for around £18m in the summer of 2011 but has yet to taste success.
He will not be doing so in the Champions League following defeat to Real Madrid but United are in the boxseat to regain their Premier League title from their city rivals and are have a FA Cup quarter-final replay to negotiate at Chelsea.
A couple of knee injuries have prevented him getting into his stride this season, and he said: "I have had a fair few injuries this season. That has been disappointing for me.
"I have got myself back fit now. Hopefully I can kick on now until the end of the season."
Young says winning becomes a habit at the business end of the season and that was exactly what he and his United team-mates were looking for, even on the training ground.
"At a club like Manchester United winning is a habit," said Young. "You go into every game wanting to win and there is a disappointment when you don't do it, and that includes during training.
"Even there it is the same winning mentality you take that on to the pitch in games.
"Overall, our results have been fantastic and the confidence from that has spread from the manager through to all the players and staff."
