Ziani wants Nantes exit
The 32-year-old has been struggling to get first-team action of late, mainly due to injury, but has become increasingly frustrated.
He missed the League Cup final after coach Loic Amisse refused to take a chance and call him up to the squad.
The midfield playmaker started out his career with Nantes but now wants to end his second spell with Les Canaris.
Ziani has held a meeting with Nantes chairman Jean-Luc Gripond and wants to find an agreement to cancel his contract at La Beaujoire.
Meanwhile, Nantes' reserve captain Denis Stinat has signed his first professional contract with the club - penning a three-year deal.
