We don't have confirmed lineups or formations from the brief — no coach names, no predicted shapes. So we're working from the known DNA of these two clubs. Celta, under whatever system they settle on, are traditionally a side that wants the ball. They'll look to play through midfield, stretch Osasuna's shape, and get runners into the half-spaces. Balaídos is a pitch that rewards that kind of intent — it's tight, it's quick, and the crowd pushes them forward.

Osasuna, by contrast, are built on the opposite principle. They're a low-block, second-ball, set-piece team. They'll sit in, make it ugly, and try to nick something from a dead ball or a moment of chaos. El Sadar is their fortress, but this is a road game, and on the road they tend to shrink into that defensive shell. That's a style that can frustrate, but it also invites pressure — and if Celta get an early goal, Osasuna have to come out and play, which is not their game at all.

The midfield battle will be the key theatre. Celta's double pivot will need to be patient, move the ball side to side, and avoid the trap of playing into Osasuna's hands with hopeful crosses. Osasuna will try to compress the centre, force turnovers, and hit on the break. It's a classic clash of styles — the artist against the grafter — and at Balaídos, the artist usually gets the nod.
