The World Cup winner was linked with a move to Camp Nou towards the end of the summer transfer window as reports emerged he wanted to escape Jose Mourinho, who has come under pressure in the early stages of the season.
"Talking about a transfer, I'm under contract," he told Telefoot. "There have been some little things with the coach, the relationship is always the same - coach and player. We have common goals, which are to win.
"As long as you don't see me in the Barcelona jersey, it's because I'm at Manchester, there will always be rumours."
"It's wonderful, the world champion's life, our life is changing, people's perceptions are changing too, I'm always the same" he added. "The change in me was made during the World Cup, I needed to become more mature, growing up, it was everything. I have a very good relationship with coach Didier Deschamps, he told me about his experience and I took it into account."
Pogba was credited with playing a big role in motivating Les Bleus to their 4-2 win over Croatia in the final. The former Juventus star told his team-mates they had 90 minutes to "write the story" and "change everything". But he says he was just saying what everyone else was thinking.
"I did not feel like doing it before. There with the World Cup, I freed myself, it's me who speaks but it's in everyone's mind," he said.
