Chelsea boss Jose Mourinho has no interest in losing Jeremie Boga.
The French winger has been linked with AS Monaco and Olympique Marseille.
But a source close to Boga told Foot Mercato: "Jeremie is under contract with Chelsea until June 2017.
"Before considering a loan, Chelsea want to extend his contract to avoid any unpleasant surprise at the end of next season.
"This is the condition that a loan will be accomplished."
