The capital club were held to a draw for the second time in a row since they beat the Premier League side in the Champions League
Thomas Tuchel paid tribute to Paris Saint-Germain for rescuing a point at Strasbourg, suggesting his players have struggled to lift themselves again since beating Liverpool in the Champions League.
PSG defeated last season's Champions League finalists Liverpool in a make-or-break European tie last week, but they have drawn against both Toulouse and Strasbourg in subsequent matches, ending their winless start to the Ligue 1 campaign.
Tuchel's PSG required an Edinson Cavani penalty to cancel out Kenny Lala's own spot-kick in a 1-1 draw on Wednesday and could have lost the game as Strasbourg pushed for a late winner.
