According to Le Parisien, talks have indeed occurred between PSG President Nasser Al Khelaifi and Leonardo over the possible return of the latter individual as Sporting Director.
Al Khelaifi is still thinking about it, but Leonardo would love to return.
PSG are considering multiple candidates for the Sporting Director role at the moment. Another is believed to possibly be Luis Campos of AS Monaco.
This would be the end of Olivier Létang as a Sporting Director and would be bad news for Laurent Blanc, who would lose some of his recruitment powers.
