On Friday night in Lisbon, Portugal's two most successful clubs meet at Estadio da Luz in a crucial game at the top of the Primeira Liga.
Benfica and Porto both boast 49 points from their 20 matches this season and, with Braga sitting only three points behind the two established powers, the latest instalment of their fierce rival could be instrumental in the title race.
Matches between the two are always hotly contested affairs and with just one defeat apiece in the league this season, Portugal's attention will be firmly focused on events in Friday's classico in the capital.
Going into the game, Benfica and Porto have an almost identical record in the league this season, though the latter have conceded three goals less than their rivals.
