Neymar was outstanding in his first outing at the Parc des Princes as Paris Saint-Germain came from behind to beat Toulouse 6-2 in Ligue 1, the hosts scoring four times in the last 15 minutes following a red card for Marco Verratti.
After being forced to watch the 2-0 victory over Amiens from the stands following his world-record €222million move from Barcelona, the Brazilian scored twice, supplied two assists – one for a stunning scissor kick from Layvin Kurzawa – and won a penalty to ensure the PSG faithful's wait to see him on home turf was worthwhile.
Blaise Matuidi made his debut for Juventus on Saturday following his €20million switch to Turin and returned to Paris for an official send off, but on the pitch PSG quickly focused on the task at hand and Neymar grazed the top of the crossbar from 12 yards in the 14th minute.
However, PSG found themselves behind when Gradel met Kelvin Amian's right-wing cross with a powerful volley that flew beneath Alphonse Areola.
The woodwork again denied Neymar when the impressive Alban Lafont tipped his header behind via the post, but the Brazilian reacted first after the Toulouse goalkeeper kept out Rabiot to slot home from six yards. Neymar then set up Rabiot, who drilled a fine finish into the bottom-right corner from just outside the box to complete the turnaround.
PSG were unable to open the visitors as freely after the restart and their task was made harder when Verratti, booked for going through the back of Alexis Blin in the opening period, caught Christopher Jullien late and was shown a second yellow card by referee Amaury Delerue.
Still, the hosts extended their advantage when Cavani thumped home a penalty awarded after Delort sent Neymar to ground with 15 minutes remaining.
The stage was set for a tense finish when Silva inadvertently headed a corner past Areola 12 minutes from time, but any nerves did not last long.
Pastore replaced Thiago Motta prior to Verratti's dismissal and he curled a sublime shot into the top-right corner to restore PSG's two-goal cushion.
It got even better for the hosts less than two minutes later when Neymar's arrowed corner was smashed beyond Lafont by a majestic volley from Kurzawa.
Neymar finished the job himself, getting away from Jullien and spinning clear of Issa Diop before beating Lafont low to the goalkeeper's left, ending a remarkable night in Paris in fitting fashion.
