Atletico Mineiro vs. Athletico PR (Sunday, 8.00pm)
A rapid upturn in form has seen Cuca's side rise to second spot in the Campeonato Brasileiro Serie A table, while their visitors sit in fifth place after a recent dip.
We say: Atletico Mineiro 2-1 Athletico Paranaense
Athletico Paranaense will certainly provide a stern test for Cuca's side, but given their eye-catching run of form, we see Atletico Mineiro coming away from Sunday's game with all three points.
Both sides are without several key players, but the Alvinegro's confidence should see them over the line in what we expect to be a close game.
Corinthians vs. Flamengo (Sunday, 8.00pm)
Sunday's visitors have enjoyed a rise up to sixth spot in the Campeonato Brasileiro Serie A table, while their opponents sit 10th after a mixed start to the season.
We say: Corinthians 0-2 Flamengo
While Corinthians do boast one of the best defensive records in the league, Flamengo could be the side to outclass them given their imposing front line and strong run of form.
The defending champions have found their groove under Gaucho, and we expect them to continue their march up the table with another convincing victory on Sunday against a side who have struggled in front of goal.
Chapecoense vs. Santos (Sunday, 10.15pm)
The Santa Catarina side are rock bottom of the table after 13 games, while Peixe are also struggling for form in 12th.
We say: Chapecoense 1-2 Santos
Santos's away form is cause for concern, but they still go into this game as heavy favourites given Chapecoense's winless start to the campaign. The visitors will have taken confidence from their cup win in midweek and should pick up the three points.
Bahia vs. Sport (Sunday, 10.15pm)
The Tricolor have lost their last four matches in all competitions, but their opponents are only outside of the relegation zone on goal difference.
We say: Bahia 1-0 Sport Recife
This might be just the game that Bahia need to regain some confidence, as Sport Recife do not tend to score many goals and have struggled on the road in 2021. Of course Leao also have a fairly tight defence, so this could be a low-scoring affair.
Ceara vs. Fortaleza (Monday, 12.30am)
This fixture, between the two most prominent teams on Brazil's north east coast who share a stadium, is commonly referred to as 'The King Derby'.
We say: Ceara 1-1 Fortaleza
Both teams have proven hard to beat this season so this game would have been a naturally tense affair anyway, but throw into the equation that they are fierce rivals and the match should be a fascinating watch; we think it is too tight to call so are predicting a draw.
Atletico GO vs. America Mineiro (Monday, 12.30am)
After a strong start to the season, Sunday's hosts have now won just one of their last six games in all competitions, while their visitors have failed to win any of their last four outings, dropping to 18th spot in the Campeonato Brasileiro Serie A table as a result.
We say: Atletico Goianiense 2-1 America Mineiro
Both sides come into Sunday's match desperate for a victory, and both will see this game as a good opportunity to do so given the opposition's poor run of form.
Given the circumstances, we see Atletico Goianiense's slightly superior quality getting them over the line, and while momentum is not a major factor considering both sides' recent struggles, a league win last time out could lift the hosts' confidence enough to fire them to another important win.
