Rashford, 18, scored a superb solo effort in the 2-1 win over West Ham United on Wednesday, taking his tally up to six goals since his debut for Man United in February.
Lingard, who came through the club’s youth academy with Rashford, insisted there is still plenty more to come with him.
“Marcus is a chilled guy, just like every other lad here. Very chilled and very down to earth, and that’s something we have at the club,” Lingard said.
“We always keep our feet on the ground. I think that mindset will have helped him when he first made his United debut.
“He works hard on and off the pitch, and I grew up with him. Well, not directly with him, as he’s been about four or five ages below me, but I’ve always seen him about and seen he has the ability to make it. He was small, like me, when he was younger, but he’s massive now!
“He was a wide player but we know he can score goals and I think striker is now his main position. Marcus is going to grow more, fill out and is going to cause defenders even more problems.”
It has been fantastic to see a young, Mancunian striker flourish in the first team and Rashford’s fairytale seems like it will not come to an end anytime soon.
Louis van Gaal has been criticised this term, and rightly so, but he deserves credit for unearthing Rashford and placing his faith in the youngster. Wayne Rooney is fit again following injury but he will find it difficult to displace Rashford in the side.
