Under former manager Jose Mourinho, Rashford was often shunted out wide to accommodate Romelu Lukaku.
But since Ole Gunnar Solskjaer took charge he has found a rich vein of goalscoring form.
The Norwegian caretaker manager says Rashford, 21, is playing the best football of his career.
And with six goals and three assists in his last eight Premier League matches, it’s hard to disagree.
Ashley Young has seen the striker come through the ranks at United from age seven, and he says Rashford looks and plays in a mature way considering his youthful age.
“Marcus just wants to learn,” Young said after Saturday’s 2-1 win over Brighton in which Rashford opened the scoring.
“He’s on the training pitch all the time and at times you have to drag him off, because he just wants to be out there. He wants to learn and that is a good thing to see in a youngster now.
“It’s fantastic to see, he’s got that hunger, that desire, he’s a winner, and when you come through the Academy here, you’ve got that in abundance and you can see that when he goes out on the pitch every day here.”
Rashford announced himself to the Premier League with a brace against Arsenal in November 2015.
And Young says he knew the striker was a special talent even before he made his debut.
“I saw it from his youth-team days, when he was in the reserves and then obviously when he was training with us,“ he recalled.
”He was a breath of fresh air. I was looking at him, thinking ‘I wish I was that spring chicken again’
“But that seems like ages ago when he burst on to the scene, and I don’t think he’s looked back since.
“Like I said, he wants to work each day and every day and he can only get better.
“I’ve said it from the time he broke into the team and even before then, he can be an unbelievable talent, he’s got the world ahead of him.
“He looks like he’s been playing for years and years. He’s a man ahead of his age.”
