Iachtchouk was born in Hrybova[3] (Hrynky Rural-rada), Lanivtsi Raion, Ternopil Oblast then Ukrainian SSR.

[4] He finished the season as the club's top scorer with ten goals as Nyva narrowly avoided relegation.

On 14 June 2007, Iachtchouk returned to Belgium, signing a two-year contract with Cercle Brugge who had just appointed his former Anderlecht teammate Glen De Boeck as manager.

[5] Iachtchouk has played for all of Ukraine's youth national teams (Under-16, Under-18 and Under-21), including a spell alongside Andriy Shevchenko for the Under-18s.

After he finally recovered he found that his dual Ukrainian and Belgian citizenship is a major obstacle to his call-up for Ukraine; while he did not see himself playing for his new home country.
