Former Manchester United defender Paul McGrath is excited by the young strike-duo of Anthony Martial and Marcus Rashford.
McGrath wrote in the Sunday World: "If I was Wayne Rooney, I'd definitely be getting worried about my place in the greater scheme of things at United.
"Anthony Martial has always looked the real deal this season and now we have this lad Marcus Rashford coming along.
"For a big buck, he can fairly cover the grass and Rashford took his goal beautifully at Upton Park on Wednesday.
"Whether it is Louis van Gaal or his successor who gets to work with these players for the next five years is one issue.
"But this duo hold out the promise of being a super strikeforce for United, or, if the club wants to cash in on one of them in a few years time, the source of a Cristiano Ronaldo-sized transfer fee.
"Where does Wayne fit in to all that now?"
