The two sides
Atletico Nacional carry a model rating of 6.77 against 6.52 for Once Caldas. The scale is anchored so that an average side in one of Europe's big five leagues sits at 6.85, and it is adjusted for the strength of each team's league, so the two numbers are comparable even across borders.
What the model expects
