PSG are waiting on Chelsea's appeal against their transfer window ban.
The Blues are sweating on a ruling, as are PSG, reports Le 10 Sport, with several potential deals in place with Chelsea.
Fullback pair Thomas Meunier and Layvin Kurzawa are both interesting Chelsea, plus defender Thiago Silva and attacker Julian Draxler.
And in the opposite direction, PSG are interested in Blues midfielders Willian and N'Golo Kante.
But any prospect of Chelsea being willing to sell will depend on them being free to sign replacements this summer.
