Swansea boss Brendan Rodgers is keen to keep hold of the Icelandic midfielder, 22, but Manchester United are also believed to be keen on the £10million rated midfielder, says the Daily Mail.
Sigurdsson said: "I've told Hoffenheim what I want to do next season and that's play in the Premier League.
"I am not worried about it at the moment, I am just concentrating on my next game.
"Hopefully things can get sorted in the summer. For now, I'm looking forward to Manchester United on Sunday."
