Win v Slovenia by 3+: Slovakia/Romania in the Round of 16. Italy/Switzerland in QF.
Win v Slovenia by 1/2: Netherlands in the Round of 16. Italy/Switzerland in QF.
Draw v Slovenia: Most likely Germany in the Round of 16. Spain in QF.
Lose v Slovenia: Most likely Belgium/Ukraine in the Round of 16. Austria/Turkey in QF.
I believe this is how the draw is shaping up
