Former Dutch under-21 international John Goossens has turned down a move to Swansea City to stay at NEC Nijmegen for the rest of the season.
Swansea agreed a fee with the Dutch Eredivisie club for the 23-year-old midfielder in December but Goossens has rejected a move to the Premier League.
His Nijmegen deal expires in the summer and he is not expected to extend it.
A statement on the club's website read: "The agent of John Goossens has today told NEC that John is not responding to the offer of Swansea City.
"NEC had already reached agreement with this club on a transfer but the player has chosen to see out the season at NEC Nijmegen."
Goossens, who is set to remain at Nijmegan until his contract expires, has been been linked with a free transfer to Dutch rivals Feyenoord in the summer.
Iceland midfielder Sigurdsson has signed for Swansea until the end of the season from German top-flight club Hoffenheim in Swans boss Rodgers' first move of the January transfer window.
And Northern Ireland under-21 striker Donnelly is set to complete his move to The Liberty Stadium from Cliftonville this week as Swansea strengthen their Premier League survival bid.
