The on-loan Liverpool midfielder has been in good form for the reigning Ligue 1 champions since his season-long switch last summer.
However, the 30-year-old has admitted that a decision on his future is out of his hands.
"I would love to stay," said the England international. "But it's not in my hands. I haven't spoken to anyone at Liverpool; I'm waiting to hear something."
Cole joined Liverpool on a free transfer in the summer of 2010.
