Chelsea manager Frank Lampard is facing a dilemma over the number of non-homegrown players in his squad.
Goal says Tiemoue Bakayoko will likely not join PSG this summer as the Ligue 1 champions close in on a deal for Everton's Idrissa Gueye.
This leaves Chelsea in a predicament as they were hoping to sell the Frenchman, who spent last season at AC Milan.
UEFA rules state clubs in the Champions League are allowed only 17 foreign players in their squad.
A further eight spots are allocated for homegrown players.
If Bakayoko stays at Stamford Bridge, he will join the likes of Kurt Zouma, Michy Batshuayi, Davide Zappacosta and Kenedy, who could spend portions of next season out of the first-team squad.
