Former Wales coach Raymond Verheijen has told Robin van Persie he should leave Manchester United in the summer.
Verheijen has blasted Manchester United boss David Moyes on several occasions for overtraining Van Persie and for his apparent 'pre-historic' tactics.
Van Persie has missed a significant chunk of the season due to niggling injuries and Verheijen has blamed his fellow Dutchman's poor injury record on Moyes.
Speaking to the Evening Standard, Verheijen said on Van Persie: "It would be better for him to leave the Man United swamp."
Verheijen believes Van Persie, Wayne Rooney and Juan Mata cannot play in the same team together as the trio take up similar positions.
Van Persie echoed Verheijen's comments after Manchester United's 2-0 defeat against Olympiakos on Tuesday as the 30-year-old told a Dutch reporter that his teammates were occupying the areas where he wanted to run into.
“The problem of keeping both RVP & Rooney is that both players have to play," added Verheijen. "Playing with 2 strikers means nr 10 Mata has to play on the wing.”
Reports suggest Van Persie is considering his Manchester United future as he is said to have become disillusioned with life under Moyes and will not want to miss out on a season of Champions League football.
