**Atlético Nacional come in hot and have owned Once Caldas historically** — this is the kind Copa Colombia clash where one team's momentum might just be the difference. 🔥

Once Caldas are unbeaten in five (3W, 2D) with clean sheets piling up, but they're walking into the ring with a Nacional side that's won four of their last five and looking genuinely sharp. The head-to-head tells the story: Nacional have 14 wins to Once's 2 over the last 23 meetings.

Key storylines:

- **Atlético Nacional's attacking threat** — a 4-3 win over Pereira shows they can score in bunches, and despite missing key players, their firepower is intact
- **Once Caldas' defensive solidity** — three shutouts in five games means they're organized, but facing Nacional's sharpness is a different test
- **Nacional's historical dominance** — 14 H2H wins is the kind of record that tends to weigh on a team psychologically

Expected lineups:

- **Once Caldas**: F. Parra, D. Londoño, J. Cardona, D. Marmolejo, J. D. Cuesta, J. Zapata, Andres Colorado, P. Gómez
- **Atlético Nacional**: L. Marquinez, A. Román, S. Velásquez, C. Haydar, W. Tesillo, E. Cabrera, F. Marin, S. Rojas

Prediction:

**Atlético Nacional 2–1 Once Caldas**

Once's form is respectable, but Nacional's recent run and historical edge make them the lean here.
