Flamengo host Gremio at the Estadio do Maracana in Brazil's Serie A on Monday, with both sides having contrasting seasons so far.Flamengo are currently third in the league, eight points off the top of the table. Renato Gaucho's side have been in incredible form, having lost only one of their last 17 games across all competitions. This will be a great opportunity for them to continue their hot-streak with a win against a poor Gremio side on Monday.Gremio, on the other hand, are currently 18th in the table and have had a disappointing season so far. Luiz Felipe Scolari's side have lost three of their last five games across all competitions and will have a huge task ahead of them if they are to get anything from the game against Flamengo on Monday.Flamengo@Flamengo_enFlamengo was back to work after last night’s win!
