Lille chairman Michel Seydoux insists Moussa Sow's switch to Fenerbahce has not been completed.
The 26-year-old had reportedly been linked with a move to English Premier League club Liverpool, but they now seem to have been gazumped by the Turkish side.
Seydoux confirmed the two clubs had agreed a fee thought to be around £10.9 million, but admitted the Senegal international had yet to agree personal terms.
"The transfer agreement is signed now," Seydoux told L'Equipe.
"There are a number of things that need to be done, including the medical."
"My information is not quite the same as those of the newspapers. I do not know which are the best, most honest and most true.
"But for now, we have no concern. At worst, if he should return, he will return. We won't lose any sleep over it."
