Manchester United forward Anthony Martial has admitted he has been forced to adjust to Jose Mourinho's "tough" management style.
The French forward had struggled to establish himself as a regular starter earlier in the season, and was at the centre of speculation that he had grown unhappy with his role at the club.
But Martial has insisted that he is now fully focused on improving and finding consistency at United this season.
"Jose Mourinho, he was tough with me, I think we didn't understand each other, but we got to know each other, we talked a lot and it's going very well," the 21-year-old told Telefoot.
"I had minor extra-sports problems, it played in my head, I wasn't very focused and now as soon as I get back on the pitch, I look to make a big impact."
Martial also stressed that his critics need to keep in mind his youth, and revealed his aims for the future.
"Some people sometimes forget my age, with talent, they wait for me to explode quickly, but everyone has their future," he added. "I want to win as many titles as possible, and with the national team I hope to establish myself in the first team and win the World Cup."
Mourinho was complimentary of Martial after his third successive start in Saturday's 1-0 victory over Brighton.
"We started again from scratch," said the Portuguese coach. "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."
