Arsenal have confirmed defender Sead Kolasinac will join the club from Schalke on a free transfer this summer.
The 23-year-old Bosnia-Herzegovina international will sign a 'long-term' deal with the Gunners when his contract at Schalke expires.
Kolasinac will become Arsenal's first summer signing when he completes his move, as manager Arsene Wenger looks to add to his squad to launch a sustained bid to win the title.
Kolasinac came through the ranks at Schalke and made over 100 appearances for the Bundelsiga outfit.
The German-born defender operates at left-back and his arrival will throw into doubt the future of Kieran Gibbs, who has yet to negotiate fresh terms at the Emirates Stadium.
