Anthony Martial has said some of his critics forget how young he is but added that he is now ready to "tear it up" for Manchester United.
Martial, 22 next month, has faced a weight of expectation since his £36 million move from Monaco to Old Trafford in 2015.
After a positive start under Louis van Gaal, the former Lyon youth academy player failed to convince Jose Mourinho last season.
But he is now producing some of the best football of his career in England, and told Telefoot: "I had some problems off the pitch [last season] that played in my head. I wasn't really focused.
"But now when I go out onto the pitch, I want to tear it up.
"Some people forget my age. Given my talent, they expected me to explode earlier. But everyone has their own pace.
"With my club I want to win as many trophies as possible, and with the national team I hope to establish myself in the first team and win the World Cup."
Martial scored just four Premier League goals last season, finding himself in and out of the United side and also losing his place in the France set-up.
However, he has been involved in 10 goals in just nine league and Champions League starts this term, returning for France in this month's friendlies against Wales and Germany.
Martial said Mourinho had been "hard with me," but added: "I think it's because we didn't understand each other that well.
"But we got to know each other, we've talked a lot, and now it's going well."
Mourinho, who gave Martial a third successive Premier League start for the first time in seven months against Brighton on Saturday, added: "We started again from scratch.
"I think we're now at the stage where I really think he can be a great, great player. After a difficult period, the definitive explosion will come."
