The 21-year-old has fallen out of the first-team picture and had a reported bust-up with manager Sir Alex Ferguson a couple of weeks ago.
Anderson has revealed he skipped training to return to his native Brazil to consider his future, due to the lack of regular action at United.
“The conversations with Ferguson are private but I have explained my situation,” said Anderson.
“I went to Brazil to think about my future and not to negotiate with other clubs.
“One of my dreams this season is to make the Brazil squad for the World Cup but the fact is that if I do not play for United then [the national coach] Dunga is not going to be interested in me.
“This is very hard for me because I need minutes on the field during the coming matches. I always had a good relation with Ferguson. He has asked me for more effort and I accept that, but I need more chances to play in the first team.”
“I have won titles in Manchester but still the people have not seen my real performance on the field,” added Anderson.
“I am not a machine. It is impossible to function 100% in each match and I accept that I have not played well during some matches but those were not significant enough to stop me playing for a long time.”
Anderson was left out of the United squad for last week’s Champions League clash with AC Milan.
“The decision not to ask me to travel to Milan was down to the coach,” noted Anderson. “I just hope I have more luck and can play in the return game.
“I am a professional footballer and my responsibility is to United. Am I happy? I would say I am optimistic. If I play more games then I will be happy. But that is normal.
“Some European clubs have asked about me but, as far as I am concerned, my future is still with United.
“I am not finished here and I’m convinced that I can offer much to this team in the decisive moments of the season.”
