Gremio come into this one in poor shape, sitting 17th and picking up just one win from their last five at home. Their home record this season tells a cautious story — clean sheets in 43% of games and an average of under one goal conceded per match — but they have rarely been involved in high-scoring affairs, with only 29% of their home games going over 2.5 goals, well below the league average of 49%.

Santos on the road are a completely different proposition. They have kept clean sheets in just 14% of away games and concede an average of two per match away from home. Their away BTTS rate of 86% dwarfs the league average of 58%, and over 2.5 goals has landed in 71% of their away fixtures. Goals look likely when Santos travel.

With no head-to-head history to lean on, the data suggests Santos's leaky defensive record on the road makes this a fixture where Gremio's conservative home style may be overturned. The visitors look undervalued given Gremio's precarious league position.
