Paris Saint-Germain coach Laurent Blanc has expressed his desire to see a collective responsibility for his team's defeat to Guingamp on Sunday.
Jeremy Pied's early goal was enough for Guingamp to consign Blanc's side to a 1-0 defeat, and the PSG boss called for his team's "leaders" to improve their performances going forward.
"The reality is that this afternoon there was a lack of collective and individual concentration," he told reporters.
"This is our problem. In a team there are leaders, and when it's not going the way you want, these leaders and also the coach, of course, they have to raise their game to ensure that the collective do too.
"Here we must say that tonight we are all put in the same bag, including me, because we have not been able to respond, although in the second half we could have equalised."
The reverse was their second this week after their 3-1 loss to Barcelona in the Champions League on Wednesday.
