Sevilla's expected lineup from their last competitive outing (against Celta) features a solid spine: Nyland in goal, a back four with Azpilicueta marshalling things, and a midfield engine of Sow and Agoumé. Up front, Alexis Sánchez and Isaac Romero give them craft and movement. That's a side that can control possession and strike on the counter. Their formation isn't confirmed, but expect a balanced 4-2-3-1 or similar shape that lets the full-backs push on.

Rayo, per the Ratingbet snippet, are likely to line up in a 1-4-2-3-1 with Cárdenas in goal and a back four of Espino, Mendy, Mumin, and Balliu. The double pivot of Gumbau and Valentín will sit deep, looking to screen the defense and spring quick transitions through García, Díaz, and Martín, with Nteka leading the line. That's a classic Rayo setup: compact, aggressive, and dangerous on the break.

The midfield battle will be key. Sevilla's double pivot of Sow and Agoumé will look to dominate possession, while Rayo's Valentín and Gumbau will try to disrupt and hit on the counter. The wide areas are where the game could be won: Sevilla's full-backs will push high, but Rayo's wide forwards, especially Isi Palazón if he plays, can exploit the space behind. Set pieces could also be a factor, with Azpilicueta's experience and Lejeune's aerial threat at the other end.

Expect a tight, tactical affair early on, with Sevilla growing into the game as the crowd gets behind them. Rayo will sit deep and look to nick something on the break. If Sevilla score first, the game opens up in their favor.
