The 18-year-old prodigy scored twice on his first senior career appearance in the 5-1 victory over Midtjylland in the Europa League on Thursday night.
In doing so, Rashford became the club's youngest ever European goalscorer, breaking the record set by George Best over half a century ago.
His chairman at his former club, the prestigious Fletcher Moss Rangers youth side, revealed to the M.E.N. that he had his pick of offers as a seven-year-old, but had his heart set on making his name at Old Trafford.
Ron Jamieson told the paper: "He's a United fan. Once they came in for him I don't think they'd have chosen anyone else. Everton, United and Liverpool, they were all clamouring around him.
"Everton were quite keen on him, they actually swamped a particular tournament in 2005 and had Everton scouts at every single game and they were quite keen for him to go down to the training ground. But he wasn't too keen, to be fair, and neither were his parents.
"As well as taking players on for a youngster, there was just something about him. It was always a spectacular goal. His interest in football just stood out. He made goals as well as scored goals. [I knew] if Marcus got his chance he would be a star and it's proved to be right."
Rashford, who has been at United since joining at the age of seven, is the latest in a long line of quality talent to make the grade at the club.
Former Red Devils stars such as Wes Brown, Danny Welbeck, and Ravel Morrison have all joined the club after being spotted shining for Fletcher Moss as pre-teens.
Meanwhile, Rangers' alumni in Louis van Gaal's current United squad include Tyler Blackett, Cameron Borthwick-Jackson, and Jesse Lingard.
