Kilmarnock manager Lee Clark is rebuilding with youth as he reshapes his squad for the new season.
Killie announced six new signings and five loan deals through the course of Friday, subject to international clearance.
Clark has signed 19-year-old Newcastle defender Jamie Cobain, who spent time on loan with Sheffield United last season, while another former Blades player, Callum McFadzean, is also joining.
The 22-year-old left-winger has represented both Scotland and England at youth level, the former thanks to a Glasgow-born grandfather.
Striker Souleymane Coulibaly arrives from Peterborough. The 21-year-old was top goalscorer at the 2011 Under-17 World Cup while playing for Ivory Coast.
Jordan Jones, who has had loan spells at Hartlepool and Cambridge, signs from Middlesbrough, while another north-east addition signs in the form of central midielder Martin Smith who arrives from Sunderland.
Also signing is 20-year-old defender Joshua Webb. The former England youth defender was a prominent member of Aston Villa’s 2013 victory in the NextGen Series.
Along with the six permanent deals, Kilmarnock have negotiated loan moves for five players.
Albanian striker Flo Bojaj and Scottish youth international defender Will Boyle come up from Clark’s former club Huddersfield.
Centre Back Jonathan Burn, 20, joins from Middlesbrough; goalkeeper Oliver Davies, 21, arrives from Swansea and 19-year-old centre-back Mark Waddington is signed on a temporary deal from Stoke City.
In addition, defender Miles Addison is on the verge of signing a three-year contract extension.
Addison, 27, who joined the club at the end of March, scored the second goal in the 4-0 win over Falkirk in the play-off final second leg.
