There are no less than three teams from Portugal in the competition's last four which means it is a guarantee that least one Portuguese team will make the final.
On Thursday, Benfica face Braga in the first semi-final hoping that it will not be a disadvantage to play the first leg at home. The Europa League has taken on an added importance for the Eagles as their domestic aspirations took a hit at the hands of their rivals Porto.
Porto, who play Villarreal in the second Europa League semi-final, romped to the Portuguese League title earlier in the month. Such has been Porto's form under 33-year-old coach Andre Villas-Boas that La Liga side Villarreal view themselves as underdogs to progress.
Porto go into Thursday's first leg at the Estadio do Dragao having won their last 12 matches, while they are still unbeaten in their domestic league having won 25 of 27 matches.
