Nice have set their price for Jean-Clair Todibo.
The France defender is expected to be sold this summer and has talked up a return to Barcelona.
Transfer expert Fabrizio Romano is reporting Nice want £40m to sell Todibo.
Barcelona, who sold him outright in 2021 for €8m, retains 20% of the player's future resale and is therefore observing developments closely.
Also watching the situation is Manchester United, who in Sir Jim Ratcliffe shares an owner with Nice.
