Club caretaker Milton Mendes's men will be desperate to turn the tide on Saturday, having experienced five defeats in their last six matches, conceding 10 goals in that time.
The only result that can be labeled as a positive was the 0-0 draw at home with Nacional, however they still failed to convert any of their 15 shots on goal at Estadio dos Barreiros.
This will be a cause for concern for Mendes; such is their growing dependence on striker Rodrigo Pinho, who was named 'forward of the month' by Primeira Liga coaches last week, after netting seven goals in nine games this season.
If Pinho can continue his rich vein of form, and others can chip in with the odd goal here and there, Mendes will know that a few good results will be enough to lift his side away from the bottom of the table
Belenenses manager Petit comes into this match knowing that his side have proved how hard they are to beat, and to an extent, showing the characteristics that he did as a player.
In the first nine games of this season, though, Petit's side have only managed two wins - one of which came last time out against Braga - while also notching five draws in that time.
Belenenses' stubbornness has been rewarded with a league standing of eighth, seven points adrift of the European qualifying places, but only four points clear of the relegation zone.
Aside from the 2018 season, when they finished ninth, Belenenses have regularly been finishing in the bottom half of the table, and Petit will be hoping to set that record straight with a top-half finish.

Mendes opted for a 4-3-3 formation against SC Farense and will likely stick with the same system.
Pedro Henrique and Caue Cecilio will contend for a starting spot in midfield, although Petit may opt for the more combative Sphephelo Sithole.
Afonso Sousa will be pushing for a start after netting a wonderful goal against Braga.
Maritimo possible starting lineup:
Abedzadeh; Winck, Andrade, Junior, Rene, China; Macedo, Bambock, Pelagio, Costa; Pinho
Belenenses possible starting lineup:
Kritsyuk; Phete, Henrique, Ribeiro; Esgaio, Edgar, Caue, Lima; S Varela, Cardoso, Sousa
We say: Maritimo 1-1 Belenenses
We expect to see a tight encounter on Saturday, with both of these sides playing with caution in recent weeks. As the game progresses, it could open up, but we expect Maritimo to put in a shift and take away a point.
