Ljungberg accused Arsenal of lacking ambition in the wake of his move to West Ham, citing the departure of Thierry Henry. And Dutchman van Persie admits his comments were not well received in the Emirates Stadium dressing room.
"If you're coming up with excuses about Thierry's departure and about promises from the club it's a bit weak.
"I was disappointed and I know a few others were as well. He had a fantastic period, he was once the best player in England, so come on and say some nice things for this club, which is fantastic."
