Paris Saint-Germain were beaten 2-0 by Monaco on Sunday, their first league loss at home in 35 matches.
Laurent Blanc lamented Paris Saint-Germain's efficiency but insisted the Ligue 1 champions "could not have done more offensively" to prevent defeat against Monaco.
After being crowned French champions for a fourth successive time last weekend, Monaco spoiled the title parade with a surprise 2-0 win at the Parc des Princes on Sunday.
Second-half goals from Vagner Love and Fabinho, who converted a late penalty, condemned PSG to their first home league defeat in 35 matches.

PSG defender David Luiz - at fault for the 68th-minute penalty - continued: "I think we haven't made a great performance. Even at the level we've played tonight we couldn't win the game. Sometime that kind of result can happen.
"[But] I think that we can see the 'real PSG' every day. That's why we have so many points [22 points] ahead of the others."
