Alianza Atl. vs Comerciantes Unidos Prediction & Betting Tips (18 September)

Alianza Atlético welcome Comerciantes Unidos to the Estadio Campeones del 36 in Sullana on September 18, 2026, in what promises to be one of the most intriguing fixtures of the Peru Liga 1 Clausura campaign. The hosts have been one of the surprise packages of the 2026 season, while the visitors from Cutervo are fighting to climb away from the lower reaches of the table. The reverse fixture back in April 2026 ended in a 1-0 win for Comerciantes Unidos, so Alianza Atlético will be hungry for revenge in front of their own fans, where they have been almost unbeatable this term.

Alianza Atlético head into this clash in excellent shape, having won three of their last five league matches. They edged a thrilling contest with Cajamarca, finishing 3-2 on September 4, and before that they produced a statement result by beating title-chasing Sporting Cristal 3-1 at home. Coach Cristián Molins has built a settled 2026/2027 squad around goalkeeper Steven Rivadeneyra, defenders Stefano Fernández, Román Suárez, José Luján and Anthony Gordillo, a creative midfield trio of Guillermo Larios, Germán Díaz and Hernán Lupu, and an attack led by José Ingratti, Jairo Molina Ospino and Cristian Penilla, with winter arrivals Cristhian Valladolid, Mariano Barreda, Franco Coronel and loanee Valentín Robaldo providing depth in the final third.

Comerciantes Unidos arrive in Sullana with patchy form, having failed to win any of their last five Liga 1 matches. Their most recent outing ended in a home defeat by FC Cajamarca, a 2-3 loss on August 28, and they were also beaten 1-0 away at Atlético Grau in mid-August, though they did manage a morale-boosting 3-1 home win over Cusco earlier in the month. José Eugenio Hernández's 2026/2027 squad is built on goalkeeper Matías Córdova, defenders Renato Rojas, Flavio Alcedo, Piero Guzmán and Alexis Cossio, midfielders Alexis Arias, Agustín Rodríguez, Rodrigo Vilca and Mathías Carpio, and veteran marksman Matías Sen up front, supported by Jean Olivares, Wilter Ayoví and Thiago Salinas. The European odds reflect the gap in momentum, with Alianza Atlético priced as clear favorites at around 1.42 to win, the draw at 3.70, and a Comerciantes Unidos victory at 5.75.

Taking everything into account, Alianza Atlético look tailor-made to extend their strong home run against a Comerciantes Unidos side that has struggled badly on the road. The Sullana side's attacking quartet has been firing, while the visitors have conceded heavily away from Cutervo, and the hosts' defensive record at the Campeones del 36 gives them a solid platform. Our prediction for this Peru Liga 1 clash is a convincing Alianza Atlético win by 3 : 0, a result that would keep their push up the Clausura standings firmly on tr
