Celje are expected to line up in their usual 1-3-1-4-2, a shape that is essentially a 3-4-1-2 with a sweeper. That back three — Avdili, Tutishkin, Hrka — will sit deep and invite Slovan onto them, then spring through the middle. Zabukovnik is the pivot, the metronome, and he will be key to breaking the Slovak press. Kvesic, Seslar and Ivanshek will look to knife through the half-spaces behind Slovan's midfield. Slovan, as expected, will stick with their 4-3-3. Takac in goal, a back four of Blackman, Bajric, Markovic and Cruz, with a double pivot of Pokorny and Mustafic shielding the defence. Barseghyan is the dangerman on the right, cutting inside onto his left foot, while Cerepkai leads the line. But here is the tactical twist: Slovan's full-backs push high, and Celje's wide forwards will exploit the space in behind. The first leg was a cagey 1-1 — expect more of the same, but with Celje more assertive at home. They will not park the bus; they will press in waves and hit on the break.
