Benfica and Porto go head to head at the Estádio da Luz tomorrow in what could well prove to be the title decider. Porto have not won anything for three seasons. Benfica are going for a 4th straight title for first time in their history. It’s a biggie.

The north vs. south “clássico” is always one of the major fixtures in the Portuguese football calendar, and with just one point separating the two rivals at the top of the table as the championship heads into the final sprint (7 matches remaining after this weekend), a victory for either team on Saturday night could prove decisive.

PortuGOAL’s series of articles analysing some of the lesser known Liga NOS clubs in depth has proven extremely popular.

Tiago Estêvão continues to cast his expert eye over the non Big Three sides in Portugal, and today’s offering is an examination of Vitória de Setúbal.

The fact Vitória are one of only two top-flight clubs outside of Benfica, Sporting and Porto who haven’t parted ways with their coach during the course of 2016/17 illustrates it’s been a tranquil and positive year for the ‘Sadinos’. Here’s how José Couceiro has achieved it.

For weeks, Porto have been waiting for their Primeira Liga title rivals Benfica to land a false stride. The moment finally arrived this weekend, but in what could proved to be a pivotal weekend in the season, the Dragons failed to take advantage.

Taking on Paços de Ferreira (only two home defeats all season) in their own back yard isn’t one for the novices of the Portuguese game, a fact Benfica fans will know all too well after their 0-0 draw on Saturday.

The stalemate opened the doors for Porto, so close to the final stretch of the season, to grab the advantage over the Eagles and go top of league table – before the meeting of the two titans in Lisbon – but Vitória de Setúbal were right on cue to derail the northern outfit in a 1-1 draw.

In the distance, Sporting went about their business quietly, as two more strikes by Bas Dost saw the Lions pick up a 2-0 victory at the Alvalade versus Nacional before the trailing storm.

In the latest instalment of PortuGOAL’s in-depth analysis of the lesser known Liga NOS teams, we turn the spotlight on one of only two clubs outside the traditional Big Three to ever win the Portuguese championship - Boavista.

At the turn of millennium the Porto-based club shocked the football world by becoming champions of Portugal and regular participants in the Champions League. But from the dizzying heights of their golden era, Boavista fell to a desperate low and years in the wilderness following demotion to the third tier on the back of corruption charges.

Having returned to the top flight three years ago, the Axadrezados are now in midst of building a competitive team again, in no small measure thanks to the astute work of coach Hugo Leal. Tiago Estêvão runs the rule over Boavista’s 2016/17 vintage.
