Lens coach Franck Haise says they'll welcome back Raphael Varane from Manchester United.
Varane is said to be up for sale ahead of the January market.
Haise said, "If Raphal wants to come back, we will welcome him with open arms.
"Whether we are ready with a contract is another matter.
"I read that it is difficult for Bayern Munich to meet his salary demands, so if it is difficult for Bayern... But maybe he wants to come back? I do not know. It's a fun discussion, but not relevant right now."
