CD Olimpia vs Firpo: match prediction on 18 September 2026

CD Olimpia are priced at 1.340 across 37 bookmakers, which translates to a 68% probability once the margin is removed. The market is underrating CD Olimpia because it has not properly priced in the first-leg result.

CD Olimpia beat Firpo 3:0 away on 11 September in the first leg of this tie. Olimpia have won three and drawn one in five, their only loss a 0-1 away at Marathon on 13 September.

Firpo have managed just four points from five games — one win, one draw, three losses — with six goals scored and nine conceded. Firpo have won just once in five, a 3-0 home victory over Inter on 6 September. They’ve lost three, including a 1-2 defeat at Metapán on 13 September and a 1-3 trouncing at FAS on 30 August. The away form is particularly poor, and they have not won a competitive match outside El Salvador since September.

The model expects CD Olimpia to score 4.5 goals and Firpo 0.3. The draw probability sits at 3%, both teams to score at 29%, and three or more goals at 85%. The three most likely scorelines are 4:0 at 13%, 5:0 at 12%, and 3:0 at 12%. Olimpia score 31% of their goals in the final 15 minutes of a match and concede 35% of theirs in that same window. Firpo concede 24% of their goals in the opening 15 minutes. Olimpia's attack is firing at the death, and Firpo's defence is leaking early.

This conclusion stops holding if Firpo find a way to control the tempo and keep the game tight. They have shown they can take points — a 1:1 draw away at Xelajú and a 3:0 win at home against Inter prove they are capable of results when they park the bus. If they manage to sit deep and limit CD Olimpia's chances, the model's expectation of 4.5 goals for the hosts becomes unlikely. A draw would suit Firpo, and given how they run the clock down, that is the main threat.

The market has missed something

There are 37 bookmakers pricing this match, and the line has not moved — CD Olimpia at 1.340, draw at 4.610, Firpo at 7.400. The market's 68% for an Olimpia win is 29 points below our 97% estimate. That is a significant edge, and it comes from one thing: the first leg. Olimpia travelled to El Salvador and won 3:0 without conceding. Firpo have one chance to respond, and their form suggests they will not.

CD Olimpia at 1.340 is the only sensible position.
