Nani has claimed Manchester United want to keep him, suggesting that he will be back at Old Trafford next season.
The 28-year-old is spending this campaign on loan at his former club Sporting Lisbon, having moved there as part of the deal that took Marcos Rojo to United.
But he is under contract at Old Trafford until 2018 and believes he has a future there, telling reporters: "The club know my value and I know they want me to stay.
"It was me who made the choice to leave the club, and it was a good decision by me because I knew if I stayed one more season at Old Trafford it would be very hard for me.
"I just need someone to believe in me, trust me and my qualities and give me an opportunity to show them on the pitch."
Portugal winger Nani figured in United's first competitive game under Louis van Gaal, coming off the bench in the opening-day defeat to Swansea, but only started 14 league games for the club between 2012 and 2014.
He has scored seven goals for Sporting Lisbon this season and added: "It's an experience I wanted a lot and needed as well, because the last two seasons at Manchester United I had so many injuries and I was very upset with a lot of things that happened to me.
"I was missing my family and friends and I wanted something new. The only opportunity I had to be happy, and Manchester United to be happy as well, was this one."
