While there will be only around 17,000 inside the Stade de Roudourou in Guingamp, the game could potentially be one of the most matched matches in the world this year as people look to see the Brazilian star in action.
PSG boss Unai Emery, at a pre-match press conference, was quoted as saying by BBC that Neymar was "physically ready to start".
Alongside Pastore will be the Brazilian Lucas Moura, who is rumoured to be staying as he has been friends with Neymar since the age of nine, and Germany captain at the Confederations Cup Julian Draxler, who arrived just previous year in a big money transfer of his own. However, it's clear that Neymar had started to get some of the Kyrie Irving syndrome and want to have a team that is built around him instead playing a supporting role next to someone who is the clear go to guy. It will make PSG a strong force, possessing one of the best attacking line-up in world football. "He's going to be able to settle in easily thanks to the other Brazilian players and he's young, so we're interested in the same things, I have no doubt".
Les Parisiens won 2:0 at home convincingly against relegation candidates Amiens SC, but they could have easily scored more as they dominated through the ninety minutes.
Spanish journal Marca and their French counterparts L'Equipe have already declared that the deal is done although this has not been confirmed by the club from the principality.
Guingamp were also strong starters as they secured a 3-1 victory at Metz, and their coach Antoine Kombouare has told his players the stakes are the same this week, even if the opposition might be of a higher profile.
Barca's scattergun approach to finding a replacement for Neymar has so far been unsuccessful with bids for Liverpool's Philippe Coutinho and Ousmane Dembele of Borussia Dortmund rebuffed. That's the easy part though, convincing Dortmund to sell given that they know how much Barca have to spend following the sale of Neymar is a different proposition altogether.
