We don't have confirmed lineups or formations for either side yet — the brief doesn't give us that, so we won't invent one. But we can paint the picture. Celta, under their usual setup, will likely dominate possession at home, looking to knife through Osasuna's lines with quick, vertical passes. They've got attacking quality in the squad — the kind that can punish a defence that sits deep. Osasuna, by contrast, are likely to set up in a low block, compact and organised, looking to hit on the counter or from set-pieces. They're not a side that will come out and trade punches at Balaídos; they'll try to frustrate and nick something.

The midfield battle will be key. Celta will want to control the tempo, while Osasuna will look to disrupt and win second balls. The wide areas could decide it — if Celta's full-backs push high and stretch Osasuna's shape, gaps will appear. Osasuna's new signing Dubasin, expected down the right, could be their out-ball, but he's still settling in. This is a game where Celta's patience will be tested, but their quality should eventually tell.
