MarítimoForm guide
Vitória Guimarães are 15th in Liga Portugal with five points from eight games: one win, two draws and five defeats. Their problem is scoring: they have five league goals all season, and seven of their eight games had three goals or fewer. They won 1-0 at Lamelas in the cup at the weekend.
Marítimo are 12th with eight points. They have won twice, beating Casa Pia 1-0 and Famalicão 2-1, but have lost to Porto, Benfica, Moreirense and Arouca. None of their eight league games had more than four goals. They also won in the cup at the weekend, 2-1 at Alcochetense.
Head-to-head
Guimarães are unbeaten in the last six meetings, with five wins and a draw, and every one of those games had three goals or fewer: 2-1, 1-0, 1-0, 2-1, 0-0 and 1-0.
Team news
Neither side has reported any absences.
Our prediction and why
Under 4.5 goals is our banker of the day. Fifteen of the two teams' sixteen league games this season had four goals or fewer, Guimarães barely score, and the head-to-head has been tight for years.
Other bets to consider
Under 3.5 goals is our second pick at bigger odds. Every one of the last six meetings stayed under it, and so did seven of Guimarães' eight league games.
