The summer signing from Arsenal produced a sublime display and, like strike partner Javier Hernandez, scored twice in United's 4-0 victory but he was also quick to acknowledge the contribution of his team-mates, including substitute Danny Welbeck.
As is regularly pointed out, Welbeck has only scored once this term with Ben Foster's superb late save against West Brom preventing him from doubling his tally. Sir Alex has stressed this is largely because the England international has been playing out of position in a wide role but adds his input has still been invaluable.
At 3-0 up against Wigan, with the points surely secure, the substitute was left clear in the box, albeit with a difficult angle for a shot, but had sufficient time to perhaps go for glory himself. Few would have begrudged a player keen to get on the scoresheet again if he had been selfish on this one occasion.
Yet not only did Welbeck do the right thing in passing to van Persie to set up a simple finish but it was something that the Dutch striker fully expected. "Danny wanted to give the ball to me so I could score," he said. "Everybody's like that."
It may seem like a simple premise but it's one that can fire United to success this term. Thinking back to another 4-0 win at Wigan, in 2011, there was an even more obvious example of the team ethic that is always guaranteed under Sir Alex.
Dimitar Berbatov, despite needing to press home his claims for a start, came off the bench to latch onto a Darron Gibson through ball and unselfishly teed up Wayne Rooney for the third goal rather than beat Ali Al-Habsi himself.
