Nani rejoined Sporting until the end of the season as part of the deal that brought Argentine defender Marcos Rojo to Old Trafford last summer.
But the 28-year-old, who has scored four goals in six European appearances for Sporting this term, says he???s keen to stay at Old Trafford provided conditions are right.
“I love Manchester United,” Nani told The Guardian.
“The only decision I made (last summer) was to play more and be me again, because I lost a lot of things there last season due to injuries and the change of manager.
“You never know the future. It depends on a lot of things. If United want me to stay then with a different mentality I think we can work well next season but there are a lot of things to discuss and see.”
Nani broke down in tears after scoring a sensational volley in the 2-0 Portuguese Liga win against Gil Vicente last Sunday.
He said the goal had meant a lot to him for personal reasons, revealing Manchester United chief executive Ed Woodward had sent him a congratulatory message after the strike.
“I receive some texts from Ed Woodward,” Nani said. “He texted me about the goal and the great season I am having here.”
