The 23-year-old, who starred for his country at the 2012 Olympic Games, is understood to be keen to leave the Scottish outfit.
He has not returned to Celtic after his summer exploits, and he now looks certain to complete a move to Swansea, according to Sky Sports News.
The fee is understood to be in the region of £6m.
