And Neymar echoed the sentiments of his coach, who suggested the former Barcelona forward had not yet hit his stride, the 26-year-old insisting the whole team were still short of their best form.
"I agree with the coach. I'm not 100 per cent, nobody is at the beginning of the season," he said.
"The high level will come between February and March when the best matches are coming. We will improve in each training session, each game.
"We must always be attentive to everything, every minute of every game.That's what we are looking for this season.
"We want to make a great PSG."
Tuchel has deployed the world's most expensive player in a number 10 role and Neymar said he is content with playing there.
"It's different. I like to play there. I can dictate the match, help my team-mates," he added.
"[Lionel] Messi plays like that at Barcelona. My function was different there. Here, I like to have the ball. I'm very happy to play like that."
With so many attacking options at his disposal, Tuchel revealed he had numerous systems that could incorporate all of his headline names and he wants to see a positive response on Wednesday.
"It's very dangerous to have Neymar, [Edinson] Cavani, [Kylian] Mbappe and [Angel] Di Maria together, it's very important for the club and the team they play and work together, that they win together.
"There are several systems with them four, that's not a problem.
"As a famous athlete said, the defeat is undervalued, because you can learn so much from a defeat.
"The important thing is the reaction and so far it is particularly positive. "
