Internacional vs Gremio Prediction, Preview, Odds: 21/9/2025

One of Brazil’s fiercest football rivalries reignites on September 21, 2025, as Internacional welcome Gremio to the Estádio Beira-Rio in Porto Alegre for their much-anticipated Serie A Betano clash. The Grenal, first contested in 1909, has long been regarded as one of South America’s most passionate derbies, and this edition promises to carry the same intensity, pride, and high stakes.

Internacional’s Revival Under Coudet

Internacional enter the derby in solid form under manager Eduardo Coudet. Their recent 2–0 victory over Vasco da Gama showcased both attacking sharpness and defensive organization, a balance the team had been seeking after an uneven start to the campaign.

Playmaker Alan Patrick remains central to their creative play, dictating tempo and unlocking defenses, while Enner Valencia’s resurgence in front of goal has added much-needed bite to the attack. At the back, Vitão and Gabriel Mercado have begun to form a reliable partnership, giving Internacional greater confidence when absorbing pressure. Full-backs Renê and Fabricio Bustos have also been influential, providing width and driving overlapping runs that stretch opponents.

Gremio’s Challenge After Palmeiras Setback

Gremio, managed by Renato Portaluppi, arrive determined to respond after a narrow 1–0 loss to Palmeiras. Despite the defeat, there were positives: the midfield trio of Pepê, Mathías Villasanti, and Franco Cristaldo continues to provide balance, combining ball retention with creativity.

Luis Suárez may not be replicating the prolific numbers of his first season, but his movement, physicality, and big-match temperament make him a constant danger. Defensively, Gremio rely on Walter Kannemann and Bruno Alves to hold the line, though their vulnerability against pacey transitions remains a concern—something Internacional will look to exploit with quick vertical play.

Tactical Battle and Key Areas

The derby is likely to be a tactical chess match. Coudet’s preference for high pressing and fast, vertical attacks could disrupt Gremio’s slower, possession-based buildup. Internacional will likely focus on exploiting the flanks, using Renê and Bustos to create overloads and deliver service to Valencia.

Gremio, conversely, may rely on experience and composure, aiming to control rhythm in midfield and draw fouls in dangerous areas. Set pieces could play a pivotal role, with Cristaldo’s delivery and Suárez’s aerial presence offering a potential route to goal. The midfield battle between Villasanti and Alan Patrick may ultimately dictate the flow of the game.

Prediction

Given Internacional’s recent form and the advantage of playing at home, they appear slightly better positioned to take all three points. A narrow 1–0 victory for the hosts seems the likeliest outcome, reflecting both their improved defensive solidity and the derby’s history of tense, low-scoring affairs.

While Suárez could still provide a moment of brilliance for Gremio, Internacional’s edge in pressing and transitions may prove decisive. Valencia or Alan Patrick could well be the difference-makers in front of a raucous Beira-Rio crowd.

The Grenal rarely fails to deliver drama, and though the scoreline may be tight, the passion and intensity on display will once again underline why this rivalry is regarded as one of the greatest in world football.

Prediction: Internacional 1 – 0 Gremio
