No new Arsenal deal - Robin van Persie

Arsenal striker Robin van Persie has announced that he will not be signing a new deal at the club.
The 28-year-old, who has a year left on his current contract, confirmed that he had met with manager Arsene Wenger and chief executive Ivan Gazidis.
But he revealed that they disagree on the way the club should move forward.
"I've thought long and hard about it, but I have decided not to extend my contract," the Dutchman wrote on his personal website.
