Julius Gibrilla Wobay scored his second goal of the season as he helped NK Olimpija to beat Koper 2-1 on Sunday away from home.
The Sierra Leone international levelled the score line for the Slovenian league leaders who are now three-point clear of the top.
Wobay, 31, scored in the 54 minutes in the second before Dennis Klinar won it for the away side in the 68th minutes.
He joined the club on 29 January 2016 a one and a half year contract.
The host dominated the last five minutes but Olimpija held on to win the tie.
