Date of birth
Stags fought off interest from several League One clubs to sign 22-year-old Adam King from Swansea City in the January transfer window.
The Swans spotted King's talents when he was a teenager with boyhood heroes Hearts and swooped to buy the versatile midfielder in 2014.
He has since enjoyed loan spells in League One, with Crewe Alexandra in 2015-16, scoring five goals in 26 appearances and Southend United the season after.
Upon his return to South Wales, King netted a hat-trick as Swansea beat Hertha Berlin 5-1 in the Premier League International Cup at the Liberty Stadium.
King was a key player during an outstanding season for Swansea U23s last term, as they sealed a league and cup double.
He has represented his native Scotland at U18, U19 and U21 levels.
