Anderson says he is not thinking about a return to Portugal and insists he's ready to fight for his place at Manchester United.
The Brazil midfielder moved to United from Porto in 2007 and although he had a positive debut season, he has been inconsistent since then.
A succession of injuries have held Anderson back and there have been suggestions he could be offloaded sooner rather than later.
However, Sir Alex Ferguson recently praised the 24-year-old for his performances of late and the former Porto star is eager to make his mark at Old Trafford.
"In Portugal, I have only ever played for Porto and if one day I came back, I would play for them," Anderson told A Bola.
"But the return to Portuguese football is far from happening. United will not let me go and I will not put myself in that scenario."
