That's according to the Daily Star, who report that Cavani will not travel with the PSG squad to Marrakech during the winter break. They claim it's the biggest hint yet that all is not well with Cavani at PSG, and that he could be off in January.
Arsenal and Manchester United have been strongly linked with the Uruguayan international, who has not settled as hoped in the French capital.
Arsene Wenger is keeping tabs on the 27-year-old forward, with reports even suggesting the Arsenal boss is willing to spend a significant portion of his budget on the £62m-rated striker next month.
A PSG statement on the club's website explains that while David Luiz, Marquinhos, Maxwell, Thiago Silva and Lucas Moura linked up with the rest of the PSG squad in Morocco as expected on Monday, Cavani and Ezequiel Lavezzi stayed in Paris.

Lavezzi & Cavani
It does not explain why both players remained in France, although Lavezzi and Cavani have both been heavily linked with moves away from the Stade de France.
Neither has hit it off since moving from Napoli, and for Lavezzi a return to Italy could be on the cards. Cavani, meanwhile, would be a huge coup for Arsenal, who have not been shy to spend big money in recent windows.
Mesut Ozil and Alexis Sanchez were top level additions from Real Madrid and Barcelona respectively, and Cavani would give the Gunners that central presence that has been lacking in their play so far this season.
