Pogba is being hammered for his low-key performance in defeat to Manchester City on Saturday.
But Ibra told SFR Sport: "Paul comes from a generation that is becoming important in France. The national team did not win the Euros, unfortunately, but the generation is strong and they will become stronger and Paul is one of them, and with what he has done, he will become even better.
"I did not know Paul before and now I know him personally, he's a boy who works hard, he wants to progress and has a good attitude, but he is still young and all the jealous people talking about him will have to swallow every word they said about him.
"Because he will only get better and he will make a name for himself around the world."
