During the 2004–05 Ukrainian Premier League season, he made 14 appearances but failed to score a single goal as Volyn finished in 8th position.

[14] Metalist also made it to the round of 16 in the UEFA Cup but lost out to another Ukrainian side, Dynamo Kyiv, on away goals after a 3–3 aggregate score.

[18] Metalist also progressed to the quarter final stage of the Europa League, losing out to Portuguese side Sporting 3–2 on aggregate.

He left the club in 2012 after six seasons to join the reigning Ukrainian Premier League champions Shakhtar Donetsk.

He made his first appearance for Shakhtar as a 77th-minute substitute for Alex Teixeira in a 2–0 victory over Metalurh Donetsk in the 2012 Super Cup.

[25] On 27 February 2014, Dević signed a four-year deal with Rubin Kazan, where he played 14 games and scored 3 goals.

[31] In June 2008, Dević became a naturalized Ukrainian citizen in hopes of playing for the Ukraine national football team.

[32] Although Dević is not the first footballer from outside the former Soviet Union to accept Ukrainian citizenship, his decision has led to numerous discussions in the media on the adoption of foreign players.

Dević also had a very successful season in 2007–08, scoring 19 goals and becoming top scorer, putting pressure on national team coach Olexiy Mykhailychenko to select him.

Nonetheless, he did cap Dević for a friendly match against Norway on 19 November 2008,[33] becoming the third naturalized citizen on the Ukraine national football team called up at that time, along with Oleksandr Aliyev and Artem Milevskyi.

In the next couple of years his match participation dropped noticeably, due to his low performance in the Premier League as well as not scoring with the national team.

Ukraine lost 0–1, with Wayne Rooney's second-half header carrying England through at the Donbass Arena in Donetsk.

[37] On the following day, however, UEFA and its chief refereeing officer, Pierluigi Collina, delivered their final verdict: match officials had erroneously denied Dević and Ukraine a legitimate goal.
