The visitors have put together a three-match unbeaten streak in Portugal's top flight, form which has kept them in fifth position in the standings.
Earlier in the season, Belenenses were sitting comfortably in mid-table as a result of losing just two of their opening nine matches.
However, despite remaining in 12th spot, recording just one point from a possible nine has left Nuno Oliveira's team looking over their shoulders to the chasing pack.
Holding the second-best defensive record in the division means that Os Azuis do Restelo have the tools to keep themselves out of trouble, but they will be eager to get a third win on the board as quickly as possible.
While their recent return looks poor, they only suffered a 2-1 defeat when playing hosts to leaders Sporting Lisbon, with that setback being followed by a share of the spoils with Gil Vicente.
On the negative side, only Miguel Cardoso has scored more than once in the league this season, his two goals being netted in his last four appearances.
Opponents Pacos de Ferreira can currently regard themselves as one of the form teams in the division having come through their last three contests without suffering a defeat.
Although those five points were collected from the current bottom three, it has kept things ticking over for a club who have ambitions to return to the European stage after a seven-year absence.
Pepa and his squad will not be thinking too far ahead at this stage of the campaign, but every win collected now will only heap the pressure on nearest challengers Maritimo.
Douglas Tanque netted a double in the most recent success over Rio Ave, taking his tally for the season to five goals from 11 appearances.

Barring any late fitness issues, that could be the one alteration to the team.
Belenenses possible starting lineup:
Kritsyuk; Esgaio, Silva, Henriques; Calila, Yaya, Taira, Lima; Teixeira, Cardoso, Sousa
Pacos de Ferreira possible starting lineup:
Jordi; Fonseca, Baizinho, Maracas, Uilton; Carlos, Eustaquio, Costa; Ferreira, Tanque, Singh
We say: Belenenses 1-1 Pacos de Ferreira
The defensive record of Belenenses is keeping the club outside of the bottom two, and we expect the home side to avoid defeat at the weekend. However, the visitors performed solidly against similar level of opposition in recent weeks, leading us to predict a low-scoring draw.
