CF Marialvas come into this one with a mixed recent run, but there is enough to suggest they can make things awkward for the visitors. They have won three of their last six, yet those results have been uneven, with draws against AC Marinhense and Oliveira Hospital and a home loss to GD Peniche in between. The bigger issue for this market is that Marialvas have also found goals hard to sustain against stronger opposition, which keeps their ceiling fairly low here.

União Desportiva da Serra arrive in much better shape, unbeaten in seven and with five wins in that stretch. Even better for an away-win case, they have kept four clean sheets across that sequence and have won their last three away matches without conceding a goal, beating SC Lusitânia and JD Lajense 1-0 and then taking the points at Eléctrico FC. That kind of control away from home is exactly what a road favourite needs.

The numbers also lean toward Serra managing the game rather than turning it into a wide-open contest. Their last six have produced only one draw and five wins, while their away scoring has been efficient rather than explosive, which fits a narrow winning profile more than a comfortable one. The earlier meeting between these sides in September 2025 ended 4-1 to Serra, although that scoreline was much looser than the recent pattern and should not be read as a template for this trip.

There is a small tension here because the xG projection is tight, at 0.8 for Marialvas and 0.9 for União Desportiva da Serra, so this is not a case of overwhelming underlying superiority. Even so, Serra’s current streak of seven unbeaten, their three straight away clean sheets, and Marialvas’ inconsistency across the last six all point in the same direction. When a team is winning regularly and not giving much away, a narrow away result is a fair call.

My prediction is Away Win at 7/5. União Desportiva da Serra have won five of their last six, are unbeaten in seven, and have kept four clean sheets in that run. Their recent away form is especially strong, with three straight road wins and no goals conceded, while Marialvas have mixed wins with draws and a home defeat in their last six.
