The likes of Ezequiel Lavezzi and Edinson Cavani have been given the nod ahead of Lucas, who has been restricted to just 65 minutes of action in the last three games.
But the 21-year-old remains confident he made the right decision when he joined the French champions from from Sao Paulo in January 2013.
"I don't regret coming. I'm very happy here, at a big club, in a wonderful city," he told footmercato.net.
"The public has quickly taken to me, which I'm very happy about and which helps me and motivates me enormously,
"It's a great experience being here. I play and I live in Europe. I'm fulfilling my dream of playing in the prestigious Champions League."
The young forward lost his place in the Brazil squad in November and now looks unlikely to make Luiz Felipe Scolari's World Cup squad this year, but remains focused on playing his way back into Blanc's plans.
"The competition for places is good, healthy. There are quality players, so all of that is good for PSG. I am doing my best in training, in games, to be able to best seize the opportunities I am given.
"Lavezzi and Cavani are more experienced. They are used to European football. I've just arrived, I'm still very young.
"I have to earn my place. What counts is that everyone pulls in the same direction."
