The Dutchman believes the homegrown talent is in the "form of his life" and playing with such joy that it is really coming across in his displays under Erik ten Hag.
With 27 club goals to his name in all competitions this term, the connections he has on the pitch are evident, including a special relationship with creator-in-chief Bruno Fernandes.
And van Persie has no doubts that Rashford is determined to keep scoring, and getting better and better.
"Yeah, you can see he’s having maybe the best form of his life," van Persie said of Marcus, during an exclusive interview with club media.
