Man Utd striker Van Persie declares himself fit for World Cup
Van Persie was withdrawn at half-time of his country's final warm-up game against Wales in Amsterdam on Wednesday with a groin issue but insisted it was only as a precautionary measure after he felt some discomfort.
"Against Wales, I stayed behind in the changing room for the second half just to be careful because the match against Spain is much more important," he said of the opening game for the Dutch at the World Cup in Salvador on Friday - a repeat of the 2010 final.
"My groin was progressively a little irritated. If it had been a sudden pain I would been concerned but you can't really even call it an injury."
