The Parisians had several opportunities to add to the scoreline in what Blanc felt was a fully-warranted victory.
"Compared to our win in Valenciennes, this one was much better," Blanc told reporters. "It was a deserved win. That's six points from two matches, and 18 points from eight.
"Still, we can do better in terms of our cutting edge; I've been surprised at the number of chances we've been creating, especially at home, but we're not putting enough of them away. If we can lift our conversion rate, we'll see some spectacular games."
