Rashford was sidelined with a back injury when the Premier League season was suspended earlier this month.
The forward said he was making good progress but admitted he was missing football.
“It’s just about patience,” he said. “I have been working hard on the bikes and following the programme that I have been given from the club.
“I have been playing Fifa, reading different types of books. It is important to keep time passing, with positive vibes and just keep smiling.”
