Laurent Blanc rued Paris Saint-Germain's profligacy in front of goal in the wake of its 1-1 Ligue 1 draw with Reims.
The reigning champion missed a number of chances to open the scoring and fell 1-0 behind with seven minutes to play via Theoson Siebatcheu.
Edinson Cavani immediately restored parity, but PSG failed to add another goal, settling for a draw, much to the disappointment of Blanc.
"All that was missing was one more goal," said the PSG coach.
"We should have been more efficient, because we created plenty of dangerous situations. But it was not meant to be. In the end, we could also have lost this match.
"We dominated proceedings, but I think our finishing was not good enough and we kept Reims' hopes alive. We kept them in the game and only have ourselves to blame.
"This was matchday six and we are still undefeated, despite the fact that we have played four away games.
"We are not happy with this draw, but we have to accept it."
