According to Spanish media outlet 'Sport', Neymar has made his feelings very clear to those in charge at the French club.
After the the Uruguayan refused to let Neymar take a penalty in the 2-0 win over Lyon on Sunday, the £198m man now sees his on-pitch relationship with Cavani as 'impossible'.
'Sport' reports: 'Neymar has already communicated to Nasser Al-Khelaifi that his coexistence with Cavani is totally impossible and he has asked for the transfer of the Uruguayan striker.'
PSG's owner now has a very tricky dilemma on his hands as he tries to rebuild the partnership between two of his world-class stars.
The dispute didn't just stop on the field, reports suggest that the pair clashed in the dressing room and had to be separated by teammates as the feud continued.
It is no secret that Neymar left Barcelona to step out of Lionel Messi's shadow and given that PSG paid a world record fee to land his signature, he expects to be the main man in Paris.
Cavani, however, has become a fan favourite since his transfer from Napoli in 2013 and it remains to be seen whether PSG will give into the demands of Neymar.
