Van Persie and Arsenal were a match made in heaven - until he left for Manchester United, that is.
The Flying Dutchman led the Arsenal line with aplomb, captaining his side to famous victories over the years while achieving glorious personal accolades at the same time. But no trophies.
And that, of course, is what irked him so - and why, at the end of the day, he moved to Old Trafford. After all, success - as well as financial gain - is the driving force behind any professional.
A year on from his move to Manchester United, van Persie would have felt justified. He carried aloft the Premier League trophy, while also finishing the top-flight's top scorer for the season. Job done, mission accomplished.
But what about now - just a few months on from that initial rush of glory ? Well, the honeymoon period is well and truly over. Sir Alex Ferguson has retired and David Moyes has suffered a rocky start to his Manchester United tenure. How must Van Persie feel now ?
Financially, the Dutchman is, of course, better off, but a look down South to the goings on over at Arsenal might have him a little unnerved. And with reason aplenty.
Liverpool's 3-1 win over Cardiff may have dislodged Arsenal from top spot in the Premier League Saturday, while Manchester United's win over West Ham may have got them back to winning ways at home - but the disparity between the two sides is clear for all to see.
Arsenal, of course, have started the season tremendously well, while Manchester United have floundered. And, on a personal level, van Persie's campaign has been fraught with injury - a fact that's particularly poignant amidst reports that the 30-year-old has clashed with his manager over his intensive training methods.
Now, with Liverpool firing from all cylinders and Chelsea, Manchester City and Arsenal taking up the other Champions League spots, there are genuine doubts as to whether Manchester United will even make the top four come the end of the season.
The most ironic thing, though, is that van Persie is the only piece missing from an Arsenal team gleaming with talent. With one of the most creative midfields in the world - and a defensive unit second to none - all Arsenal manager Arsene Wenger needs now is another striker to share the workload with Olivier Giroud. Then he will have the complete squad.
If only van Persie had waited - Arsenal would have been virtually unstoppable. But if my aunt had balls, she'd be my uncle.
Is Robin van Persie Arsenal's missing link ?
