The 21-year-old reportedly fell out with Old Trafford supremo Sir Alex Ferguson after revealing his frustration at being left out of the Community Shield squad that lost to Chelsea on penalties earlier this month.
Following the departure of Cristiano Ronaldo to Real Madrid for a record £80 million, the Brazilian international is expecting a more regular place in the Red Devils' starting XI, but has so far only started once this season in the 1-0 defeat at Burnley.
However, the former Porto starlet has revealed he does not want to leave the club, and is ready to knuckle down and attempt to establish himself as a first-team regular.
"I believed that I would play in the Community Shield but that is forgotten now," he said in the Daily Mail.
"I thought that, without Cristiano Ronaldo around, I could play more and that has been my challenge from pre-season onwards.
"But the coach decides the teams and to discuss this with him is foolish because he is the chief. I do not want to leave United.
"Sir Alex Ferguson has demanded a bigger effort from me and I accept that because to get into this United team is very complicated and difficult for any player."
