The 20-year-old, who prefers to play as a no.9, has played most of his game on the wings for the Red Devils.
England great Alan Shearer doesn't think Marcus Rashford can become the main striker at Manchester United.
Rashford played alongside Harry Kane through the middle for England against Spain on Saturday and opened the scoring in the home side's 2-1 defeat at Wembley.
However, the Premier League's record goalscorer on 260, is convinced Rashford has the attributes to become a world-class striker but can't see that happening under Jose Mourinho at Old Trafford.
"As long as Romelu Lukaku stays fit he is not going to get a starting spot as the lone striker at Old Trafford," the former England captain told The Sun. "As long as Jose Mourinho is the manager, there is not going to be two up top.
"Even if Lukaku did not play, my money would be on Alexis Sanchez being moved into the middle and further forward.
"And would Mourinho really turn to Rashford if he needed another striker? Or would he go to the transfer market for a tried and trusted ready-made goalscorer?
"Rashford has been played so long in a wide position in a three, that it does take time to readjust to his natural position.
"Time is not a great commodity in football nowadays. I am not advocating Rashford moves away from Old Trafford. It is a great club to be at. But if he wants to achieve an ambition to be recognised as a great goalscorer it is just not going to happen there.
"He would need to move with the assurance that his next club will make him the main man, the striker, the one up top or one of two. Then I truly believe he would develop into a goalscorer."
