Reports emerged this week that the United forward is frustrated at his lack of consistent game time under Jose Mourinho.
And it was suggested the 19-year-old may contemplate leaving the club at the end of the season if his position doesn’t change.
However, Express Sport understands Rashford is happy at United and is not stalling over a new deal.
The England international penned a four-year contract last May with no discussions taking place over another.

Despite having to battle with the likes of Zlatan Ibrahimovic, Anthony Martial and Jesse Lingard for a place in the team this term, he remains part of Mourinho’s long-term plans.
The source said: “It’s absolute nonsense to suggest Marcus wants to leave.
“I’m sure he’d like to start every single game if he could, but he knows that’s impossible.
“He’s making good progress under one of the greatest managers of all time and has a massive future ahead of him at United. There’s no chance he would be sold.”
