And Blanc feels his side have grown as the season has progressed, believing they have recovered quickly from a stuttering start.
"With two draws to start with, you could say the opening to the league campaign was complicated," he told the club's official TV channel.
"But you got the feeling that the team was getting physically stronger, and that was confirmed by what happened afterwards.
"Now we're not only winning our games, but also trying to play good football. And I like that, because it corresponds to how I perceive football."
Despite a strong season so far, Blanc still believes there is room for improvement and feels it is key that his troops find their shooting boots ahead of the visit of Bastia.
"We still have to handle our good moments better, put away our chances more often," the World Cup winner argued. "We can still score more goals, just as we did against Benfica (in the Champions League)."
PSG had no problems in the goalscoring department last season as they put seven goals past Bastia across both fixtures - winning 4-0 away from home, before picking up a 3-1 win in front of their own fans.
In fact, this weekend's hosts will be confident that they can come out on top on Saturday, with the visitors last recording victory on Parisian soil in 2003.
PSG have a few high-profile injury concerns going into the tie, with Zlatan Ibrahimovic and Gregory van der Wiel having nursed knee problems in recent weeks, and Thiago Silva (thigh) still sidelined.
