That is according to Red Devils legend Paul Scholes who has been impressed by the 19-year-old in recent outings, including tonight's 2-1 Europa League win over Anderlecht in which he scored an extra-time winner.
Rashford also shone in the weekend's Premier League victory over Chelsea as Ibrahimovic sat on the bench and the youngster will now be awarded more chances after the superstar Swede appeared to seriously injure his knee at Old Trafford tonight.
"He will get his chance in the next few weeks looking at that. It doesn't look great," Scholes said on BT Sport.
"Although he has walked off which is hopefully a good sign.
"We saw on Sunday the effect Marcus had on his own, he was a real handful against Chelsea.
"If Zlatan does miss out we know we've got a top player who can come into his place.
"Zlatan wasn't great tonight. He missed a few chances."
