The Portugal international joined Manchester United from Sporting Lisbon in the summer of 2007 for a fee in the region of €20 million (£17m) and experienced a fruitful first season in England.
However, Nani failed to make an impact last term as he found himself behind Park Ji-Sung in the club's pecking order.
Reports in England have suggested Nani could be offloaded by United, but the player has rejected stories the club are looking to cash in on him.
"My future is at Manchester United, of course," he told the Portuguese press. "It is a privilege to be at a club like this.
"I won one more title (last season) and I am very happy to have won it for these two consecutive years.
"I was born to play football and I feel fine, although I did not play much. I will not leave Manchester United, nor will I be loaned out.
"I will see out my contract."
