Sigurdsson joined Swansea during the January transfer window after struggling to make an impact in the Bundesliga with Hoffenheim in the first half of the campaign.

He has created a huge impression at the Liberty Stadium, scoring six goals and being named the Premier League's Player of the Month for March.

Swansea boss Brendan Rodgers has already expressed an interest in signing the Iceland international on a permanent basis in the summer.

However, Hoffenheim coach Markus Babbel revealed earlier in the week that he is keen for the 22-year-old to be involved in his plans for next season.

Sigurdsson has previously suggested he does not want to return to Hoffenheim to sit on the bench and the former Reading youngster is awaiting developments regarding his future.

"I still have a couple of years left on my contract at Hoffenheim, so there is not much I can do at the moment," Sigurdsson told The People.

"It's out of my hands."
