The 26-year-old joined United in a £16million deal from Aston Villa earlier this summer.
“I’ve always had confidence in myself and believed that I could play at the highest level,” he told Inside United.
“Some people said I couldn’t, but they also said I couldn’t play for England. That doesn’t bother me though – I’ve got confidence in myself to know what I can do.”
Young has revealed that United made contact with him in January about a move to the club.
“At the time we were in a sticky situation at Villa and in a battle to stay up, so the clubs said they’d talk again in the summer and see where things were at,” he added.
“There were other clubs interested but as soon as I heard about the interest from United I just wanted to get here and sign. I knew it was the right club.”
