After eight prolific seasons at Arsenal, the Dutchman has quickly settled into life at United, scoring 13 goals in 19 games and looking at home in the red shirt.
But in a revealing interview with MUTV, the striker admitted he’s still not satisfied and warned there’s more to come from him this season.
His perfectionism even extended to taking his share of the blame for the goal that was wrongly disallowed at Reading last weekend after his shot crossed the line.
“I am happy with the way I’ve started, but on the other hand, I should have scored four or five more, so that’s something for me to work on,” the 29-year-old said.
“At Reading I could have taken a small touch and put it in instead of shooting. So I’m always thinking like that: how could I have done better?
“I try to improve however I can, on and off the field, by doing little things in the gym, extra work after training, practising headers, crossing and finishing.
“I’m not satisfied yet. If you look at the stats, they’re OK. But I want more goals, more assists, more wins; I want to go for everything possible this year.”
Players often talk about the familial spirit at United and van Persie is no different, crediting the club’s welcoming atmosphere and the staff for his positive start on the field.
