The 23-year-old made his United debut almost five years ago, scoring a hat-trick.
The England striker is keen to play on at Old Trafford for another decade.
“I hope I’m still at United when I’m the same age as guys like Ryan, Scholesy and Gary Neville,” he told the Sun. “I’ve always said that as long as United want me, I’m happy to stay.
“I don’t want to leave. I love the club and have no reason to even think about moving. I’m sure I’ll be here for a long time.”
