The 23-year-old has recently been linked with the likes of Manchester United, Liverpool and Inter Milan.
“In the world of football it is not possible to speak about the future, but in this moment I do not have any motive to leave Sporting Lisbon,” he said.
“I am happy right now, because all that counts is getting a goal.
“But now it is necessary to focus on the match with Manchester City.”
Van Wolfswinkel only joined Sporting from Dutch side Utrecht last summer.
