A big game is in store for Portuguese football fans, as two of Portugal's biggest games will face off to kick off proceedings on Friday. This game could have some serious repercussions on the title race, especially given how tight things are between Portugal's "Big Three" sides.
On the opposite end of the spectrum, struggling Belenenses just may have been given a chance to drag themselves out of the drop zone, as they take on fellow floundering Vizela to wrap up matchday 13 on Monday.
Will we see some changes in the league table by the time the dust settles?
Here's all you need to know ahead of matchday 13.

Primeira Liga games you won't want to miss on matchday 13
Portimonense vs Porto: As things stand, Porto are on top of the table heading into this round. On paper, they do appear to be the favorites against sixth-placed Portimonense. However, the hosts have won their last two games to recover following a two game losing streak, and the pressure will be on the visitors to get things right here. That's especially given that Benfica and Sporting CP will be playing later in the same day in a match that could really shake things up in the league table.
Benfica vs Sporting CP: A mouth-watering clash is in store as two of Portugal's "Big Three" sides go head to head on Friday. Both Benfica and Sporting CP are the only unbeaten sides remaining in Portugal's top flight, and as it stands, just one point separates the two teams. Benfica presently sit in third place, on 31 points, having suffered their only loss of the season in their last five games.
By contrast, Sporting are joint-tied on points with Porto at the top of the table, albeit behind the Dragons due to their inferior goal differential. The visitors are on a five game winning streak, and Porto possibly moving three points clear depending on the outcome, both teams will be eager to battle it out for a much needed three points.
Vizela vs Belenenses: Two struggling sides will go head to head in a desperate battle for points on Monday, and it will be very interesting to see who - if any - comes out on top. The visitors have won just once all season, while the hosts have also won just once so far this term and have earned just three points from their last five games.
