The Primeira Liga continues this Friday with one team still retaining a perfect 100 per cent winning record.

After four rounds, only one team remains unbeaten. That side is Benfica, who have picked up 12 points out of 12 from their first four games and could potentially increase their lead over the chasing pack should they beat Vizela on Friday.

Here is all you need to know ahead of matchday five.

Key Primeira Liga fixtures for matchday five

Benfica vs Vizela: After four rounds, Benfica are the only side to still maintain their perfect winning record. With 12 points, the Eagles could temporarily go as much as five points clear over second-placed Sporting Braga should they, as expected, beat Vizela in the first game of matchday five on Friday evening.

Estoril vs Sporting CP: Sporting CP have suffered back to back losses, which has seen the Lions slide down the table into a very disappointing 13th spot. As such, the pressure will be on to turn things around when they face Estoril on Friday evening, but given that their hosts have earned four points from their last two matches, that might be easier said than done.

Sporting Braga vs Vitória Guimarães: Sporting Braga have had an impressive start to the season, and with ten points, are only bettered by Benfica in terms of the table standings. Last season saw them finish in fourth spot, behind Portugal's "Big Three" and they will certainly look to take advantage of Vitória Guimarães's recently bad patch of form when the two sides meet on Friday.

Gil Vicente vs Porto: After seeing their perfect streak snapped during a shock 3-1 loss to Rio Ave last round, how will Porto react when they travel once again, this time to face Gil Vicente on Saturday? The loss was that much more shocking considering that Sérgio Conceição's side are the reigning champs and Rio Ave were promoted from the second division last season. Certainly, many eyes will be on this match; Porto do have the vastly superior head to head advantage but in football, anything could happen.
