The Hoffenheim midfielder has scored seven goals this season on loan at Swansea and has told the German club that he wants a permanent move to a club in the English top-flight
The midfielder has scored seven goals in 17 appearances since arriving at the Liberty Stadium in the January transfer window after a frustrating few months at the Bundesliga side.
"I'm not worried about my future," the Iceland international told Sky Sports.
"My thoughts haven't changed. I've told them [Hoffenheim] what I want to do next season and that's play in the Premier League and hopefully things can get sorted in the summer."
Swans’ boss Brendan Rodgers has confirmed he would like to keep the player who he previously managed at Reading, while his performances have also reportedly attracted attention from Manchester United and Arsenal.
But the 22-year-old still has two years left on his contract at his parent club, who have previously suggested they want him back next season and will demand a fee in the region of £10 million for him.
"I don't know what will happen. We'll have to wait and see," Sigurdsson concluded.
"I'm just focused on the next game and the next game is a good one.
"I'm playing every game and have scored a few goals as well so I'm very happy here."
