Sikan began playing football in Polissya Zhytomyr as a child. As a teenager, he began playing for Karpaty Lviv. He made his debut in the Ukrainian Premier League in a match against Zorya Luhansk on 12 August 2018,[1] but then played in competitions for reserves. Later in the 2018-19 season, Sikan was loaned out to FC Mariupol.
Sikar joined Shakhtar Donetsk in 2019, debuting with a victory against his former club Karpaty on 4 August 2019. That season he played 7 matches for the senior side and made a debut at continental club competitions on 26 November 2019 in an away tie against Manchester City. Struggling to get on a scoreboard, Sikan was placed back in competitions among reserves.
For the 2020–21 season, Sikan was loaned again to Mariupol, where he made his debut in the Ukrainian Cup competitions.
On 25 October 2022 in a UEFA Champions League game while playing for Shakhtar Donetsk against Celtic he missed an open goal at his mercy which was one of the worst misses in football history.
On 4 October 2023, he scored his first Champions League goals, by netting a brace for Shakhtar in a 3–2 away win over Royal Antwerp. His performance earned him the title of Player of the Match.[3] A month later, on 7 November, he scored the only goal in a 1–0 win over Barcelona at Volksparkstadion in Hamburg.[4]
