Van Persie has been in very good form for the Netherlands at the World Cup so far.
The forward is currently enjoying a productive World Cup under van Gaal having found the net for the Netherlands on three occasions, and helping them secure their passage to the knock-out rounds of the tournament with a game to spare.
During his first season at Old Trafford, Van Persie's goals had a big say in Manchester United ending up as champions but in his second season, under David Moyes, he failed to replicate that form and had a couple of injury problems.

In his Daily Mirror column, Savage wrote: "There is no denying that LVG has brought the best out of RVP at the World Cup. That magnificent header in Holland's amazing demolition of Spain was a flying Dutchman restored to the peak of his powers.
"Van Persie has looked a different player to the lost soul who struggled for his best form under Moyes last season. He looks fitter, hungrier, stronger and has played with so much more confidence than at any time since his first season with United.
"Three goals in his first two games of the tournament has restored the spring in Van Persie's step. If this is what Van Gaal can do for the striker's esteem, United fans are going to feel like they have signed a new player in August."
As the statistics suggest, it's not a case of Van Persie declining, it's case of getting the best out of him, injuries permitting. His goalscoring record under David Moyes, on paper, looks quite impressive.
But he does look more like the striker that made them pay around £24 million to Arsenal for in the summer of 2012, and more like the player that is capable of coming up with the moments that end up being so crucial to his side's season.
If he performs as well for United under Van Gaal as he does for his country, then there will be a few worried looks on the faces of opposing defenders.
