Gil Vicente vs. Belenenses (Monday, 7.00pm)
With only a point separating them amid a congested bottom-half of the Liga NOS table, both Gil Vicente and Belenenses meet on Monday night in need of a rare win.
Success at Famalicao last week could provide momentum for the 11th-placed home side, while Petit's visitors lost at home to ruthless leaders Sporting Lisbon.
We say: Gil Vicente 1-1 Belenenses
As Belenenses rarely give much away - and have beaten Braga and troubled Sporting in recent weeks - Gil Vicente will have their work cut out to claim maximum points at home.
A low-scoring draw appears the most likely outcome, as both sides look set for a drawn-out battle for Liga NOS salvation on the cards.
Our tipster partners are predicting a double chance bet on a home win or draw.

Portimonense vs. Farense (Monday, 9.15pm)
A battle at the bottom of Portugal's Primeira Liga takes place on Monday night, as Portimonense welcome fellow Algarve club SC Farense to Estadio Municipal de Portimao.
Both sides are looking for a first win in three games, as they aim to pull away from the basement of a tightly-packed Liga Nos table.
We say: Portimonense 1-1 SC Farense
The incredible congestion at the lower end of the Primeira Liga standings demonstrates just how closely-matched Portugal's 'also-rans' are in this strange season.
With neither side prolific in front of goal, a hard-fought draw is the most probable outcome in Portimao this Monday, as both sides continue a season-long campaign for survival.
Our tipster partners are predicting a double chance bet on a home win or draw.
