ENGLAND (REUTERS) - Arsenal have signed Schalke 04's Bosnian international left-back Saed Kolasinac on a free transfer, the Premier League club said on Tuesday.

Kolasinac will start pre-season training with Arsenal in July "subject to the completion of all regulatory processes", the north London club announced on their website (www.arsenal.com).

Schalke confirmed in a statement that the 23-year-old had signed a deal with the Gunners which runs until 2022.

Kolasinac will be competing with two senior left-backs, Spainiard Nacho Monreal and England's Kieran Gibbs, for a first-team spot.

He represented Germany at youth level before deciding in 2013 to play for Bosnia, his parents' homeland, and has collected 17 caps to date.
