Neymar, 27, was pictured arriving at Barcelona's El Prat airport on Thursday ahead of his date in court, where he is suing the La Liga champions over an unpaid loyalty bonus of 26 million euros ($30.69 million).
As Neymar scored a bicycle kick winner amidst boos, Manchester City slumped to their first defeat after a 15-match winning streak and Inter Milan took an early two-point lead over reigning champions Juventus.
Neymar, who has probably become the most unpopular player in the PSG team following a failed transfer to Barcelona over the summer, found the net two minutes into stoppage time with a sensational overhead kick.
Lionel Messia also said he had no plans to quit the Catalans any time soon after it was confirmed by the club that his contract contains a clause that allows him to decide at the end of each season whether he wants to leave for free.
Barcelona's Neymar is all set to leave the club after serving his best four years. He scored 105 goals in 186 appearances for Barcelona. His best season for the club came in 2014-15, where he managed to score 39 goals. He is likely to join Paris Saint Germain for a record fee.
