Winger Nani has insisted that he has not paid too much attention to speculation that Manchester United are eager to recall him from his loan stint at Sporting Lisbon.
The Premier League outfit allowed the 27-year-old to rejoin his first club on a season-long basis during the summer, with centre-back Marcos Rojo having made the switch in the opposite direction.
However, Nani's return of six goals in 13 outings has resulted in reports that United boss Louis van Gaal was keen for him to return to Old Trafford in January.
When asked about those rumours, Nani told reporters: "I do not think there is such a clause. It is a matter for other people to solve.
"It's good to feel the warmth of the United fans. They ask for my return, but I'm thinking only of continuing to work. This is one of the best moments of my career and I hope to continue it."
Nani joined United from Sporting in the summer of 2007 and he has gone on to make over 200 appearances for the Red Devils.
