Pierre van Hooijdonk has reignited his feud with former Feyenoord teammate Robin van Persie.
The pair didn't see eye-to-eye when they were together in Holland and ex-Nottingham Forest star Van Hooijdonk told Sportweek of the Arsenal man: "I think Van Persie a brilliant footballer, but as a person, he is still not really stable.
"This impression hasn't changed for me."
"I think that it is striking, that after all those years at Arsenal he still has a problem."
