Fisnik Asllani opened the scoring for the visitors in the sixth minute when he latched on to a throughball from Mergim Vojvoda and fired past Slovenian keeper Jan Oblak.

Kosovo doubled its lead in the 64th minute when Slovenia's Zan Karnicnik turned a cross past his own keeper.

Slovenia's job was made tougher when second-half substitute Petar Stojanovic was sent off for picking up two yellow cards within 10 minutes of the restart.

Kosovo stands second in Group B on 10 points, three behind Switzerland, which crushed Sweden 4-1.

The Balkan nation hosts the group leader on Wednesday (AEDT) but lags far behind on goal difference.
