Reports in Europe have claimed that Neymar is unhappy with the situation at PSG and is keen on returning back to the Camp Nou where he announced himself to the world, forming a formidable attacking trio alongside Lionel Messi and Luis Suarez.
PSG are also believed to be lining up a move for Bayern Munich striker Robert Lewandowski but it will require the Ligue 1 side to sell Cavani to comply with Financial Fair Play restrictions.
Despite the Brazilian leaving for Paris in the summer, Barcelona players remain close with Neymar. At that time, Neymar was trying to move out of Lionel Messi's shadow.
Many concerns were raised over the summer when Barcelona was forced into a record-breaking transfer deal once the release clause of their Brazilian forward was met. Neymar departing for Paris Saint-Germain was seen as a great loss for Barcelona.
Mundo Deportivo report that the 26-year-old informed his old club of his wish prior to PSG's Champions League defeat to Real Madrid on Tuesday. He also didn't expect the level of Ligue 1 to be so inferior to La Liga.
Barcelona, however, is not the only club Neymar is reportedly targeting as a potential way out of Paris Saint-Germain.
As the Parisians lost 5-2 to Real Madrid on aggregate to exit the Champions League at the last-16 stage, their star man's future may be thrown into question with stories continuing to suggest Neymar could make a sensational switch to Real Madrid. He is said to still have a good relationship with one of the coaches, who was at the club from 2014 to 2017.
Neymar is now recovering from a foot surgery in Brazil after suffering a broken metatarsal last month.
The forward is now recovering from foot injury, sustained in a 3-0 league win over Marseille, in a bid to be fit for the World Cup in Russian Federation this summer.
