Sky Sports understands Swansea City are poised to sign Adam King after the Hearts teenager underwent a medical on Monday.
King has been a long-term target for Swansea, who are believed to have made an approach for his services at the end of the summer transfer window in 2013, but saw an offer knocked back by Hearts' administrators.
The 18-year-old only made his Hearts debut in December in the 7-0 defeat by Celtic in the Scottish Cup and he has since gone on to appear twice in the Scottish Premiership.
He can play in midfield or in defence, and King has been attracting interest from several clubs, in addition to Swansea.
However, it appears that Swansea are close to snapping up King after he was in south Wales on Monday to have a medical ahead of joining Michael Laudrup's side.
