The Brazil international has again been linked to the La Liga champions, with Madrid captain Sergio Ramos saying the door was open for the 25-year-old.
Neymar made a world-record move from Madrid’s fierce rivals Barcelona to PSG in August and has scored 11 goals in 12 games in all competitions for the Ligue 1 giants.

Morata, who left Madrid for Chelsea in July, said Neymar joining his former club would be hard – but not impossible.
“I think it is difficult because of his past,” the Spain international told El Larguero .
“But we have already seen that in Madrid there is no impossible.”
Zinedine Zidane’s men are eight points behind rivals and La Liga leaders Barcelona through 11 matches this season.
