Grêmio host Vasco da Gama on Sunday with barely a point separating the two sides and only three places standing between 15th and 17th in the Brasileirao table. The hosts sit on 22 points from 20 matches, one ahead of Vasco's 21, and both carry identical poor form ratings that leave this fixture open to the team that can arrest their slide first. Grêmio have won 5, drawn 7 and lost 8, while Vasco have registered 5 wins, 6 draws and 9 defeats, leaving neither with momentum to lean on.

Grêmio's recent run reads as 1 win, 1 draw and 3 defeats across their last 5 matches, scoring 8 and conceding 9 in that span. They have found the net in all 5 outings but kept 0 clean sheets, and the lone victory came in a club friendly against Cruzeiro. Their competitive sequence includes a 1-1 home draw with Fluminense, a 2-3 away defeat to Bolívar in the CONMEBOL Sudamericana, and a 1-2 reverse at Mirassol in the league. Over a 7-match sample this season they average 1.44 expected goals per game from 12.4 shots and 4.7 on target, with 52.1 percent possession and clean sheets in just 10 percent of fixtures. They have failed to score in 0 percent of matches, which speaks to consistent if modest attacking output, but conceding 1.30 per game across the season has left them with a goal difference of minus 4.

Vasco da Gama arrive with 1 win, 2 draws and 2 losses in their last 5, scoring 6 and conceding 5. They drew 1-1 at home to Mirassol and 2-2 away to Independiente Medellin in the Sudamericana, either side of defeats to Vitoria and Atletico-MG in which they failed to score. Their sole win in that stretch was a 3-0 home success over Barracas Central in May. Across a 10-match sample they average 1.31 expected goals from 16.6 shots and 5.4 on target per game, holding 53.9 percent possession and managing clean sheets in 20 percent of outings, though they have blanked in 30 percent. At 1.55 conceded per game over the season, their defensive record trails Grêmio's and accounts for the worse goal difference of minus 8 and the lower league position.

The head to head record across the last 10 meetings shows Grêmio with 5 wins to Vasco's 3 and 2 draws, though the most recent encounter in March saw Vasco win 2-1 away. Before that Grêmio took November's fixture 2-0 at home, and the July 2025 meeting finished 1-1. The 5 itemised matches have averaged 2.0 goals, with both teams scoring in 4 of the 10 overall and over 2.5 goals landing in 4 of 10. Four of those 5 detailed fixtures saw the home side prevail or the match drawn, suggesting venue matters in this pairing.

With form scores separated by just 0.23 in Vasco's favour and both rated poor, the contest hinges on which side can address their defensive frailties first. Grêmio's unbroken scoring run and home advantage stack against Vasco's greater willingness to blank but superior head to head result on their last visit. The league positions, goal tallies and recent returns all point to a narrow, low-scoring affair with the slenderest of margins deciding which side can climb clear of the bottom half.
