Young was on target with a fine low strike in the 2-0 victory over Cardiff City on Tuesday but claims he won't be resting on his laurels as he looks to cement a regular spot in David Moyes' side.
"You have to be on the ball," he told ManUtd.com and PA Sport. "You have to put in big performances every week. We have a big squad and we can rotate the team. When you are playing well, getting goals and assists, you are there in the manager's thoughts.
"We have competition for places and that keeps you on your toes. You want to keep playing well and training well, because that is the only way to keep yourself in the team."
The Reds' attack was further strengthened against the Bluebirds, with Robin van Persie finding the net on his return from injury and record signing Juan Mata making his debut after arriving from Chelsea.
"He is a goalscorer," Young said of van Persie. "You put him in the box and he will score, and he has done that again.
"There will be a lot of talk about Juan's arrival and the fact that we have broken the the transfer record for him, but he looks like he has been here for years. It was his first game but he has gelled straight away with the way we play. He is going to add something special to the squad."
