For the task of repeating Georgia's feat and toppling mighty Portugal, head coach Matjaz Kek can call upon two stars to provide inspiration at either end of the pitch.
In goal, captain Jan Oblak is one of the world's best shot-stoppers, while up-and-coming RB Leipzig striker Benjamin Sesko offers both presence and power up front.
The latter will again be paired with former Benfica and Braga marksman Andraz Sporar, though neither has scored since arriving in Germany despite playing all three group games.
Kek employs a traditional 4-4-2 formation, with Udinese's Jaka Bijol helming the back four; Timi Max Elsnik and box-to-box runner Adam Gnezda Cerin are generally favoured in central midfield.
However, the ex-Maribor coach will be forced to make one change to a settled starting lineup, as Erik Janza must serve a suspension for picking up two yellow cards: Alanyaspor defender Jure Balkovec is set to deputise at left-back.
Slovenia possible starting lineup: Oblak; Karnicnik, Drkusic, Bijol, Balkovec; Stojanovic, Elsnik, Gnezda Cerin, Mlakar; Sporar, Sesko
