The coach showed his disdain for his opponent's tactics as PSG easily dispatched of les Gones and defended the absence of French players in the line-up
A double from Zlatan Ibrahimovic and strikes from Thiago Silva and Edinson Cavani ensured les Parisiens a comfortable victory and Blanc suggested his side were never going to be put under any pressure from a Lyon side that had been set up to limit any damage from the start.
"Lyon were never going to be dangerous," the PSG coach told Canal Plus after the final whistle.
"The problem was that they came out with the intention of getting behind the ball and that prevented us from getting forward.
"We changed our system to rectify that but we could have stuck with the same formation and still have won the game."
The home side also set a record this evening as the first side in Ligue 1 to field a starting XI without a single Frenchman.
Blanc defended his decision not to start a single homegrown player, saying that some of the players in the squad needed a rest and, if anything, the result only served to highlight the strength and depth at his disposal.
"[Blaise] Matuidi is tired and we must be careful with players who have spent a lot of energy," the former France boss added. "We are lucky to have a quality team so we can afford to rest some of the French players."
PSG's next Ligue 1 clash is away to Evian on Wednesday.
