PSG host Borussia Dortmund on Tuesday in their first match in a heavyweight Champions League group which also features AC Milan and Newcastle United.
The French title-holders have endured one frustration after another in the competition in recent years, with a defeat by Bayern Munich last season seeing them go out of the Champions League in the last 16 for the fifth time in seven years.
Beaten finalists in 2020, PSG went backwards after that, the decision to sign Lionel Messi ultimately backfiring.
Messi and Neymar have now left the Parc des Princes after a close-season clear-out which continued up to last week, when Marco Verratti was sold to Qatari side Al-Arabi for a reported 50 million euros ($53.3m).
Verratti spent 11 years in Paris and was, at his peak, one of the finest midfielders in the world.
