Pogba came in for some criticism during Les Bleus' 3-1 win against Italy on Friday night and was booed when he made his way off the field as a second-half sub.
"Not everything was successful [against Italy], but he helped the team be well organised," he told Telefoot. "I don't question Paul's potential. If I called him up, it's because he's indispensable for me.
"I know what he is capable of. He has to raise his level of play. I have confidence in him, as I do in my other players."
Pogba struggled for form at club level in 2017-18, although he did end the Premier League campaign with six goals and 10 assists.
