In terms of star quality, veteran Italy goalkeeper Gianluigi Buffon may give Neymar a run for his money at the Parc des Princes this season.
The 40-year-old former Juventus great is expected to start ahead of Alphonse Areola and Kevin Trapp for PSG this term, although Tuchel acknowledged he has a tough decision to make.
"Gigi is a top player, professional and a legend," he said. "He is like that in the locker room with all the staff. He is humble and polite.
"He's a good influence for our team. And regarding the three goalies, it will be a tough decision for me.
"All three of them are quite talented and have the personality to be number one. There are still two training sessions before the match and I will speak with them.
"But if there's one thing I've learned as a coach, it's not to make decisions too early."
