Nice chief Francesco Farioli concedes they could lose Jean-Clair Todibo this week.
The France defender is target for Manchester United as Harry Maguire considers accepting a move to West Ham.
Farioli admitted: "These rumours have existed since the start, so we've developed antibodies against them be it the team or myself.
"There are a few days left we'll see.
"There is a chance that he stays, and I would be happy because he's a quality player and he would be very hard to replace.
"I hope the rumours stay rumours."
