The French World Cup winner is set to sign a six month contract with the Trotters before the end of the transfer window but Canard says nothing has been settled just yet.
"We have to think about everything before making a choice, nothing is certain yet.” said agent Stephane Canard.
Meanwhile Olympique Marseille defender Philippe Christanval could also pen a loan contract before Monday afternoon's deadline. The French defender has been a long time target of Bolton manager Sam Allardyce ever since he played for Barcelona.
