Thomas Tuchel hopes to see "another" Paris Saint-Germain against Manchester United after again condemning a perceived poor attitude in their draw with Bordeaux.
PSG let a two-goal lead slip to lose at Monaco last week and Tuchel said afterwards his side "did not play seriously enough" and "completely stopped playing football".
Although the reigning Ligue 1 champions bounced back by scraping past RB Leipzig in the Champions League in midweek, it was more of the same against Bordeaux.
PSG trailed to debutant Timothee Pembele's 10th-minute own goal but looked to be cruising after Neymar scored a penalty - his 50th Ligue 1 goal - and Moise Kean quickly added a second.
However, former PSG player Yacine Adli equalised and Tuchel's men were perhaps fortunate to escape with a 2-2 draw.
Ahead of a vital European trip to United on Wednesday, this was not ideal preparation.
"We can not play without effort as we did in the second half," Tuchel told Canal+. "The first half was okay, we played simple.
"But we lacked the seriousness to finish this match, to kill it. We lacked determination in the area.
"We lacked everything in the second half: discipline, effort... everything. It was worse than against Monaco. We lacked effort, discipline, attitude.
"Normally I always protect my team but today I totally disagree. It is not necessary to lose points a second time like that after Monaco. We lost the second half and it is absolutely our responsibility - mine, too.
"We must see another PSG against Manchester; it is not possible to play a match of this level.
"I don't understand why we don't take our responsibilities, why we don't play more seriously."
PSG had just five shots in the second half to Bordeaux's 14, despite leaving Neymar and Kylian Mbappe on the pitch for the duration.
Neymar, playing his 58th Ligue 1 match and reaching 50 goals in 21st-century record time, could shoulder little of the blame.
He had 97 touches, fewer only than Leandro Paredes (112), and created three chances on top of his five shots.
The Brazil forward offered a more considered assessment of the stalemate than his coach but agreed PSG had to improve against United.
"We played a tentative match; we managed to score goals but missed some details," Neymar said. "We have to improve that. It's a championship in which we usually win a lot of matches.
"Yes, we know the importance of Wednesday's match; as against Leipzig, it's decisive. We will try to play our best game, play well.
"We have to improve certain details, play as a team, organise better."
