Jemson does not believe that United star has nailed down his best position at United and believes that he should be playing primarily as a centre-forward at this stage of his career at the club.
In his 271 appearances for the club, Rashford has scored a total of 88 goals, while also providing 56 assists.
Speaking exclusively to This Is Futbol, he said: “Rashford. I don’t know what his best position is.
“Surely to god, he should be a number nine by now. He’s got years of experience on him but is he a left winger cutting in? I don’t know. I don’t think he knows what his best position is.”
