The 33-year-old's current deal with the French outfit expires this summer, but Boudjellal has claimed that there is a new offer on the table.
"I'd sign him for four years if he wanted to. He knows that if I extend it, it's not for bad reasons. It's just that he's an excellent player. Only he can say, it's he who decides," he told reporters at a press conference.
It is understood that Wilkinson will announce his future plans in March.
