The 19-year-old forward has featured heavily this season and, according to ClubCall, Jose Mourinho and his backroom team fear that could lead to him sustaining an injury.

United are about to enter a crucial period of the season, with Premier League fixtures against Liverpool, Tottenham and Chelsea before the next international break.

Rashford was not afforded a rest during the latest round of England fixtures, starting both games against Slovenia and Lithuania.

Mourinho’s medical team believe too much time on the pitch coupled with his age could lead to problems.

ClubCall claim a muscle injury is the most likely issue facing Rashford.

And that could result in him being named as a substitute at Anfield on Saturday.

Anthony Martial has impressed in his cameo appearances this term and could start in Rashford’s place.

United have a number of injury problems ahead of the trip to Liverpool.

Marouane Fellaini (knee) is definitely out after picking up an injury on international duty while Paul Pogba (hamstring) is a long-term absentee.

Phil Jones, Romelu Lukaku and Michael Carrick are expected to be fit, despite carrying knocks.

Marcos Rojo and Zlatan Ibrahimovic (both knee) are not due back for a number of months.
