Neymar was on sparkling form, scoring twice and forcing Fode Ballo-Toure's own goal but Monaco gave as good as they got in an absorbing contest in Paris on Sunday.
Nevertheless, Neymar – the world's most expensive footballer – is backing head coach Thomas Tuchel's strategy.
"We scored three goals. I think that it worked well," Neymar told reporters.
"We have quality, we know it. I think you made a mistake with this question but I responded."
Neymar believes Sunday's test will stand PSG in good stead as they once again compete for multiple honours, with Tuchel's old employers Borussia Dortmund their last-16 opponents when the Champions League resumes next month.
"This was a very difficult match," the Brazil international added. "We knew that we were going to encounter difficulties because they have a good team, with quality.
"It was a good test. We are happy. This was not the best match of our season. We are going to improve each time to pull off a great campaign."
