Nani still hopeful of more years with Manchester United Getty

Manchester United winger Nani says he is ready to return to Old Trafford this summer and still firmly believes he is good enough to excel in the Premier League.

Nani, 28, rejoined boyhood club Sporting Lisbon on a season-long loan in the summer of 2014 as part of the deal that saw Marcos Rojo join Louis van Gaal's United side.

After two seasons marred by injury and inconsistent form, the Portugal international has enjoyed a revival of sorts in his homeland both domestically and in European competition.

With three years remaining on his current contract in Manchester, Nani hopes his form has convinced Van Gaal he is deserving of another opportunity, although he has also refused to rule out staying at Sporting.

"I am a Manchester United player and I must return," Nani told Portuguese newspaper O Jogo. "I can never say it is impossible [staying at Sporting]. I believe I am now more confident to complete for a place in whatever team it is. I am able to play in a more competitive league. But nothing is concrete yet."

Nani arrived at Old Trafford in the summer of 2007 for a fee of £14m ($21m). To date, he has made 230 appearances for the club, scoring 41 goals. While enjoying his return to Portugal, the wideman has never closed the door on returning to Old Trafford.

But United remain heavily linked with a number of wingers ahead of the summer transfer window, something that could threaten his future at the club.

PSV Eindhoven star Memphis Depay has been widely tipped to become an addition to Van Gaal's squad before the start of next season. The 21-year-old is the top scorer in the Eredivisie with his goals helping PSV to their first league title since 2008. Liverpool also remain interested in the Netherlands international.
