There have been plenty of questions surrounding the future of van Persie at Old Trafford, with speculation suggesting that the former Arsenal man is unhappy at the club and could be sold in the summer.
Juventus, Chelsea and former club Arsenal have all been linked with moves for the Dutchman, who will be 31-years-old by the start of next season, and some have suggested that United boss David Moyes should cash in on the striker this summer rather than keep an unhappy player at the club.
And those rumours could potentially intensify after it was confirmed in the Manchester Evening News that van Persie's seven-year-old son Shaqueel is training with United's cross-city rivals Manchester City.
An unnamed source told the MEN; "There's quite a bit of surprise about it. You would have thought that if they were going to be with anyone it would have been United."
It's questionable as to why van Persie, who could surely get his son into the club given his standing in the squad, would choose to let Shaqueel join City rather than United - raising questions about the proficiency of the United youth coaching, though it's worth point out that van Persie junior is only seven, and is at this moment too young to sign for a team.
Van Persie has spoken of his son's ability before, particularly whilst with Arsenal where he admitted that the Gunners had invited Shaqueel to training before, and also stated that the two are somewhat similar.
"I honestly have to say that he has got a lot of talent for football," he said. "I recognise a lot of stuff of myself in him. His coach is really great. Arsenal has invited him a couple of times to come and play there but he likes it at his club. He's sensitive for a good atmosphere. Just like me."
