The ex-Arsenal striker arrived at Old Trafford in 2012 in a highly controversial move, and proceeded to score the goals that won United the title, making a mockery of Gunners fans who suggested he only left the Emirates Stadium in order to get more money.
But now, it seems that the relationship between van Persie and new manager David Moyes isn't fantastic, particularly after the Dutch striker criticised the tactics used by the former Everton boss in United's 2-0 loss to Olympiacos last weekend.
“Our fellow players are sometimes occupying the spaces I want to play in,” Van Persie said. “And when I see that it makes it difficult for me to come to those spaces as well. So that forces me to adjust my runs, based on the position of my fellow players and, unfortunately, they’re often playing in my zones. I think that’s a shame.”
Those comments have set tongues wagging about the potential of van Persie leaving United in the summer, and Allen - the manager known as 'Mad Dog' - believes that van Persie should be one of the first casualties in United's anticipated overhaul.
"It's a very fine line between confidence and arrogance. Clearly Van Persie wants out. Aged 30 and with a poor injury record he's the first one who should be shown the exit door in the summer," said Allen.
"Quite clearly that type of attitude rubs off on the rest and there will be factions and cliques at Manchester United moaning and complaining, talking about how Sir Alex Ferguson used to do it this way or that way. The bottom line is, several of those players are well past their best," Allen added.
Allen has a reputation for being a hot headed manager, and it's unsurprising for him to say such a controversial thing, but there may be something to his comments. Van Persie has made some disruptive comments, yet doesn't seem to be getting much stick from United fans - but how would they react if Wayne Rooney had made the same remarks? If van Persie is unhappy at Old Trafford, then maybe Allen is right and United should sell the star - regardless of how much fans want the Dutchman to stay.
