Prediction Internacional vs Flamengo 2025 – Betting Tips for the Copa Libertadores on 21/08/2025

Match context and recent form

Porto Alegre will host a high-stakes Round of 16 tie at Estadio Beira-Rio on 21/08/2025 as Internacional welcome Flamengo under the watch of referee Esteban Ostojich. The two sides arrive with contrasting momentum and a very fresh reminder of how this rivalry currently reads: their clash on 17/08/2025 ended 1-3 in favor of Flamengo, a result that underlines the away side’s confidence going into this Copa Libertadores knockout fixture. Internacional’s recent string has been patchy — a mixture of wins, draws and defeats that shows fragile consistency — while Flamengo stride into this tie with a much stronger recent record on paper, seven wins from their last ten matches according to the provided form summary.

Tactical edge and statistical clues

Numbers tell a clear story about how each team plays and what to expect. Flamengo dominate the attacking metrics; their total shots (91) and shots average (13) outpace Internacional’s 69 total and 9.86 average, and Flamengo’s attacks average (125.43) and dangerous attacks average (58.71) highlight a side that generates abundant threat. Their defensive profile also looks sturdier in the provided data: five clean sheets and a goals conceded away figure of 1 suggest Flamengo can carry both control and ruthlessness on the road. Internacional, meanwhile, show respectable home goal scoring (8 goals at home) and an ability to create chances — their shots inside the box (48) match Flamengo’s — but their clean sheet count of 2 and a less consistent form line give pause.

The most recent meeting is another decisive clue: Flamengo’s 3-1 victory at Internacional featured a standout performance from Pedro, who earned the best player rating in that match. That result, combined with the bookmakers’ pricing, paints Flamengo as the team with the edge: odds reflect that sentiment with Flamengo priced at 2.45 (approximately a 40.82% implied probability), while Internacional are longer at 3.20.

Prediction and betting tips

This tie feels tilted in Flamengo’s favor. Their recent head-to-head success, superior attacking volume and defensive resilience create a compelling case that they can again impose themselves at Estadio Beira-Rio. Internacional have home advantage and the capacity crowd behind them, but the statistics supplied — from shots and attacking output to clean sheets — lean toward Flamengo controlling the contest.

Betting suggestion: Back Flamengo to win (1X2 market). The away win at 2.45 offers value given Flamengo’s recent form, superior attacking metrics and the decisive 3-1 triumph in their most recent encounter.
