The Frenchman has guided his team to an impressive domestic campaign, with PSG holding a seven-point lead over Monaco heading into their final league fixture at home to Montpellier on Saturday.
Last month also saw them lift the Coupe de la Ligue trophy with a 2-1 win over Lyon, while Blanc also steered the club to a UEFA Champions League quarter-final.
"We are satisfied with the work done by the players and the staff," he said.
"In terms of points, the game, the outcome is positive, but also as regards the operation.
"Next season we will try to be more efficient, we will try to do better and keep moving forward."
"It's not my problem," he said. "When I arrived there was a sports director. I enjoyed working with him, he (was) called Mr Leonardo. After, he left.
"Then I worked with Olivier (Letang). If the club wants to take an athletic director, I do not interfere in it."
