The 23-year-old England international has been a key part of the United set up since making his debut for the club in February 2016.
He graduated from United’s academy and has transformed his on-field achievements off the field as well.
Rashford has been rewarded with an MBE and an honorary doctorate degree from the University of Manchester recently for his fight against child poverty during the coronavirus pandemic.
“I never look beyond Manchester United and as a kid I have never looked beyond Manchester United,’ Rashford said after being honoured with a Sports for Social change award by the Sports Journalists’ Association.
“In my mind it wouldn’t sit right for me to be pulling on another shirt. I just want to do the best I can. Hopefully I am here for a long time.”
"All the good things that have happened this year it's come from Manchester United giving me the opportunity as a kid," he added.
"I don't just remember the last year or the last five years, I'm talking about the times when nobody in my family drove and I had to get to training, and United had people to come and take me to the training ground and take me back home.
"When I was six, seven, eight years old, I'm talking about the times when they put me into accommodation when my mum was struggling at home, when I was 11 years old and I was up there until I was 16, 17, so it's a lot deeper than what people see sometimes.
"I think people only see some of the stuff that's been happening since I've been in the first team, but the bond that I have with United is much greater than just these last five years, and it will forever be greater than my actual career.
"They're the reason that I've become a footballer, they've given me an opportunity to express myself and find out that I had talent in football."
Rashford has won one FA Cup, one Europa League and one League cup during his time at Old Trafford.
