BRINJE GROSUPLJE, Slovenia (Interstat) — An undefeated Slovenian Cup run for third-division side Brinje Grosuplje faces its ultimate test on Wednesday when top-flight powerhouse NK Maribor visits.

The cup matchup pits a dominant lower-league side against a traditional giant. Brinje Grosuplje enters the contest with a perfect 3-0-0 record in this competition and is an astonishing 13-0-1 across all competitions this season. They are riding high after a 1-0 road victory over Tabor Sezana last Friday.

NK Maribor, a perennial force in Slovenian football, has played a far lighter schedule. Their sole competitive match this season was a 13-0 demolition of NK Jurovski Dol in the cup on Sept. 23, giving them a 1-0-0 record in all competitions.

Despite the stark contrast in divisions, Brinje Grosuplje’s relentless form suggests they will not be intimidated on their home pitch. Their offense has been explosive, with multiple high-scoring victories, including an 8-1 win over NK Jevnica and a 6-0 win over Bela Krajina.

However, Interstat’s game simulator projects a tight, defensive battle, favoring the top-tier quality of Maribor with a 1-0 final score.

The winner will advance in the Slovenian Cup. Brinje Grosuplje will return to league play on Nov. 2 against NK Kety Emmi&Impol Bistrica.
