Pogba, after two years out of action, has been a second-half substitute for his first two games back.
Ahead of this weekend's clash with Brest, Pocognoli said of the former Manchester United and Juventus star: "He's been training tirelessly.
"He's giving 100%, without holding back. There's still work to do on his basic fitness, but that's normal because it depends on the match. Everything is going well; his performance against PSG was in line with what we've been working on. We'll have to gradually increase his playing time.
"But it's the same for every player; we need to think about the team first to see what he can bring on the pitch."
Pocognoli also said: "Against Paris, when he came on, we were leading 1-0 with 10 men against 11. It wasn't easy, but it was the best solution given his qualities, his experience, and the work he's done in training.
"So it was a logical choice. He still needs some time before becoming a regular starter, but when we feel he's ready, we can take another step forward.
"In any case, he's very clear-headed, objective, and positive. This is important, and that's why he was able to play, because he shows great character. He listens to his body and everything we're doing; it's all positive."
