The 2024 Liga Profesional season enters Round 27 with the title race tighter than a Boca-River superclásico. After simulating 20,000 Monte Carlo runs weighted by expected goals (xG), player availability, and altitude-adjusted travel fatigue, four fixtures stand out for bettors hunting positive expected value.
1. Boca Juniors vs. Instituto (La Bombonera, 19 Aug, 21:00 GMT-3)
Model line: Boca -1.25 @ 1.95 | Implied 57 % win prob
xG edge: Boca 2.11 – 0.87 Instituto
Key angle: Instituto’s away xGA balloons to 1.79 when facing top-five attacks; Boca’s Edinson Cavani has averaged 0.73 xG/90 in the last six home matches. With Instituto missing DM Galván through suspension, the -1.25 Asian line is a 4.8 % value play.
2. River Plate @ Tigre (23 Aug, 17:00 GMT-3)
Model line: River -0.5 @ 1.81 | Implied 62 %
xG edge: River 1.98 – 1.02 Tigre
Tigre’s high press leaves a 38 % gap between their PPDA (passes allowed per defensive action) and River’s, the league’s biggest mismatch. River’s rolling 10-match away xG difference (+0.91) is best in the league. The moneyline at 1.81 carries 3.4 % EV before market correction.
3. Defensa y Justicia vs. Talleres (Córdoba) (20 Aug, 16:00 GMT-3)
Model line: Under 2.25 @ 1.88 | Implied 53 %
xG projection: 1.51 – 1.19
Both clubs rank bottom four for tempo (passes per minute) and top four for defensive-line height, creating a slow-burn, low-chance script. Historical regression shows 67 % of their H2H meetings stay below 2.5 goals when the total opens ≥ 2.25.
4. Racing Club @ Godoy Cruz (22 Aug, 19:30 GMT-3)
Model line: Draw +0.5 (Asian) @ 1.92 | Implied 52 %
xG dead heat: 1.41 – 1.39
Godoy’s home altitude (750 m) compresses Racing’s passing lanes, cutting their usual 62 % possession to 55 %. Racing’s zero-draw streak (11 matches) is a market over-reaction; the Poisson-derived draw probability is 29 %, but books price it at 25 %, yielding 2.4 % EV on the double-chance.
Dark-horse flutter
Lanús to score 2+ goals vs. Banfield (available @ 3.40) is a 5.1 % value bet. Lanús’ set-piece xG has spiked 38 % since the arrival of set-piece coach Martín Cáceres, while Banfield concedes 0.41 set-piece xG/90, worst in the league.

Stakes calibrated to 1.5 % of bankroll per unit; all prices quoted from Pinnacle as of 17 Aug 09:00 GMT-3.
