The hosts, who are 11th in the Primeira Liga table, come into this one on the back of back-to-back defeats to Farense and Belenenses, and they will look to end this dry spell on Sunday.
Newly-promoted Nacional have had a decent start to life in the Portuguese top flight, and while they have not performed above expectations, they have not been poor either.
As earlier stated, Vitor Vinha's men currently occupy 11th in the league following their first-placed finish in the Segunda Division last term.
They have done a great job of grabbing wins against the sides below them in the league table, with their five wins this campaign coming against Farense, Gil Vicente, Tondela, Famalicao and Boavista.
Nacional have also shown signs they can compete with the big guns, after holding both Pacos de Ferreira and Benfica to draws.
The Madeira side have struggled with consistency, and after a run of four straight defeats at the turn of the new year, they quickly bounced back and went on a four-game unbeaten run.
However, they come into Sunday's clash on the back of two straight losses, after falling to a 3-2 defeat against Farense and a 2-1 loss away to Belenenses last time out.
They now host Braga, who are coming off a disappointing Europa League exit, following a 5-1 aggregate defeat to Roma, but are unbeaten in six games in the league.
The visitors have picked up 14 wins from 20 matches, and are currently seated third in the Primeira Liga table with 43 points, one point below second-placed Porto.
While their last outing was a 3-1 defeat to Roma in Rome, their last league outing was a 4-2 home win against struggling Tondela.
Braga come into the clash on the back of five straight wins against the hosts, while they are also unbeaten in the last 11 meetings, dating back to 2013.
Their last meeting ended in a 2-1 win for the Arcebispos, with Fransergio and Iuri Medeiros giving the visitors a two-goal advantage before Nuno Borges grabbed a consolation goal for Nacional in the 86th minute.

With Brayan Riascos the only absentee for the hosts after picking up a muscle injury, Freire has the luxury of a near-fully-fit squad to choose from, and we expect a few changes to the starting XI from last time out.
Nuno Borges and Azouni are expected to return to the fold after serving a suspension last weekend, while in the absence of Riascos, Kenji Gorre, the team's second-highest scorer in the league, will once again lead the attack.
On the other hand, the visitors go into this fixture without several key players through injuries.
Portuguese midfielder Andre Castro is ruled out indefinitely with an unknown injury, while Francisco Moura (knee), David Carmo (ankle) and Iuri Medeiros (knee) are also all out of contention for Sunday.
Nacional possible starting lineup:
Piscitelli; De Souza, Henrique, Correia, Vigario; Borges; Thill, Ramos, Camacho; Mendes, Rochez
Braga possible starting lineup:
Matheus; Tormena, Silva, Borja; Esgaio, Elmusrati, Gaitan, Galeno; Piazon, Sporar, Fransergio
We say: Nacional 1-4 Braga
With 43 points from 20 games, Braga have been impressive so far in the domestic league, and they take on a struggling Nacional side who are just three points above the drop zone. Carvalhal's men are also on a six-game unbeaten run, and we predict that they will grab all three points on Sunday with a handful of goals.
