Maritimo, meanwhile, are on a similar poor run themselves and will bid to end a three-match winless streak to finish the season in the top half of the table.
It has been a very solid campaign for both of these sides, who were relegation threatened last year.
Both teams ended just one point ahead of the relegation playoff, but have managed to stay up comfortably this season with Maritimo strongly pushing for a top-half finish.
They have done this by turning their fortunes around up front, with goals from Joel Tagueu proving crucial for the side, who had one of the worst offensive records last season.
Should they win on Saturday, then this will confirm their finish in the top-half of the table, provided there is not a nine-goal swing in favour of Pacos Ferreira in 10th.
However, they do not have the momentum and at the moment Maritimo are stumbling towards that top-half finish, with just two wins in their past 10 matches.
Nonetheless, Pacos de Ferreira's form is quite similar, and with a 2-1 win against Portimonense in this season's reverse fixture, Maritimo have every chance to finish this season on a high.
In terms of Saturday's visitors, despite their recent form it has still been a positive season for Paulo Sergio's side.
They have not looked like relegation fodder via a pretty solid backline, with many other teams posting worse defensive records.
In addition, should they win this weekend and other results go their way, Portimonense could end this season with a top-half finish.
To do so, Sergio's men must beat Maritimo by more than the 2-1 scoreline they were on the wrong end of in the reverse in order to gain the upper hand in the head-to-head record, while also hoping that other results go their way, with three teams currently splitting the sides.
It is also up front where Portimonense still struggle, so that might make it difficult this weekend considering the solidity of the Maritimo defence.
So, Saturday poses one final chance for these sides to end their recent poor form and finish the season positively, in what has been a much better campaign for both teams.
Portimonense will still be without Adewale Sapara, who sustained an injury in March's defeat to Benfica.
Other than that, Portimonense have a clean bill of health, with no players suspended for Saturday's match either.
Meanwhile, it is likely that Welinton Junior will once again lead the Portimonense forward line, following his goal in the 3-2 defeat to Sporting last weekend.
As for Maritimo, right-back Claudio Winck should return from suspension and slot straight into his side's defensive line.
This means Maritimo, too, have a clean bill of health meaning they could have a full strength lineup on display.
Maritimo possible starting lineup:
Silva; Winck, M.Costa, Junior, V.Costa; Beltrame, Rossi, E.Costa; Guitane, Joel, Vidigal
Portimonense possible starting lineup:
Samuel; Moufi, Henrique, Relvas, Lazaar; Da Costa, Jocu, Carlinhos, Angulo; Nakajima; Junior
We say: Maritimo 1-1 Portimonense
Considering it is a game between two sides who are comfortably mid-table, it is unlikely this fixture will be a classic. Both sides are on poor form and will be looking forward to the end of the season, so a draw is the most likely outcome.
