Cork City F.C.
In 1998, Karyaka transferred to CSKA Kyiv, trained by the ex-Dynamo Kiev midfielder Vladimir Bessonov. With CSKA, he was able to participate in the UEFA Cup Winners' Cup, first playing against Cork City F.C., and consequently, against FC Lokomotiv Moscow. Yet in the next season, things did not work out as well, and he spent the majority of the 99/00 season playing for the reserve team.
