Nicknamed 'Os Lobos' (the wolves), the Portuguese qualified for their first Rugby World Cup in 2007, and have experienced unprecedented success in recent years.
The national team was surprise winners of the 2003/4 European Nations Cup, and have continued to record impressive results.
The IRB Sevens World Series circuit has allowed the Portuguese players to demonstrate their competence to the wider rugby world and the Portuguese team have become an established power in the abbreviated form of the game competing at every IRB Sevens event.
Portugal will be eager to bounce back from their 21-13 loss to Canada in Lisbon last Saturday and ironically both squads travelled to Ireland last Sunday, with the Canadians to play Ireland at Thomond Park Stadium this coming weekend.
