Manchester United want star winger Marcus Rashford to gain more muscle to avoid injuries.

The Red Devils star is set to return to first team action in the coming weeks, ahead of schedule, following shoulder surgery after Euro 2020.

Rashford was plagued by back, ankle, and then a shoulder issue over the past 12 to 18 months.

According to the Daily Mail, United believe Rashford must gain more muscle in his upper body to avoid injuries in the rough and tumble of the Premier League.

The winger has gained muscle in his lower body, but lost muscle in his upper body due to being unable to perform certain exercises after shoulder surgery.

He could be in the squad as United take on Leicester City in the Premier League on Saturday.
