The Portuguese star has been linked with Manchester United and Atletico Madrid after a terrific season in Bundesliga.

Silva, 25, has scored 19 goals in 21 league appearances this season.

"I've heard rumours, but that is it," Silva told Portuguese outlet O Jogo. "Rumours are rumours.

"At the end of this season, it's something that gives me more motivation to work, it's a sign that what I have accomplished has borne fruit and the path has been good."
