Ghana youth striker Abass Issah scored for the second successive time for Slovenian giants Olimpija Ljubljana who beat ND Gorica side 2-0 on the road.
Issah gave his side the lead in the 40th minute before Blessing Eleke added the second with a quarter of an hour left.
Olimpijia have now won all their two league matches and on top of the table.
Abass was a member of the 2015 Ghana U17 team which got disqualified from playing at the African Junior Championship for fielding an unqualified player.
