London: Arsene Wenger’s first activity in the transfer market since signing a new contract last week is to secure the services of Bosnian international defender Sead Kolasinac on a free transfer.

Kolasinac, who turns 24 later this month, joins the FA Cup winners from Bundesliga side Schalke 04 and will compete with Nacho Monreal for the first choice berth.

“Sead Kolasinac will join us this summer on a long-term contract,” read a short statement on the club website Tuesday. “Subject to the completion of all regulatory processes, the defender will start pre-season training in July.”

Kolasinac, born in Germany but to Bosnian parents, made 94 Bundesliga appearances for Schalke and played over 20 Europa League and Champions League matches for the ‘Royal Blues’.
