Chelsea, on Wednesday, submitted a €75million offer to Leicester City for Wesley Fofana.
According to L’Equipe, the bid was immediately rejected by the Foxes.
Fofana has become a priority for Blues boss, Thomas Tuchel, who is looking to replace Andreas Christensen and Antonio Rudiger.
However, Leicester’s official stance is that Fofana is not for sale.
The 21-year-old wants to join Chelsea, as he would realise his dream of playing in the Champions League.
Chelsea are expected to return with a bigger bid for the France defender and hopefully finalize a deal.
