While losing 5-1 in the first leg was always a disaster, to say that Porto were rather lucky for that scoreline would be an understatement considering how rampant they have been this season, both domestically and in Europe.
Nevertheless, football as we phrase it has seen too many surprises to be underestimated and while we do not deny that Porto are huge favourites to make it for Dublin, a spirited showing from Juan Carlos Garrido's men should not be counted off tonight as Live Soccer Tv provides 10 interesting statistics and match facts ahead of the Iberian clash at the Madrigal.
1) Villarreal have been absolutely prolific at home this season, scoring 20 goals and winning all seven European matches at El Madrigal. Better still, they have only conceded four goals in that process.
2) Meanwhile, this piece of statistics over shines the above one. Porto's success in Europe this season has largely been down to their impressive form away from home. Villas-Boas' men have won all seven outings away from home in Europe this season.
3) Villarreal's chances pretty much depend on whether they can get an early goal or not. Statistics show that they have not scored a goal in the opening 15 minutes of all their European matches this season.
4) Should Villarreal fail to score in the first half, expect a comfortable progress for Porto considering how they tend to rack in goals during the second half. 23 of their 34 goals in Europe have all come in the second half of their matches.
5) Falcao is on the brink of beating Jurgen Klinsmann's record for the most number of goals in a UEFA Cup/Europa League campaign. Both of them are currently tied at 15 and should Falcao score tonight, he will not only boost Porto's final hopes but also rewrite the history books.
6) While both these teams have been paired for the first time in their history, Porto have gone against Spanish opposition on numerous occasions. Recently though, Porto have had some luck in Spain, undefeated in their last five visits there with three wins and two draws.
7) Porto have had the most number of shots on target in the Europa League this season with 93 shots. That gives a very good average of 7.5 per match. Expect a flurry of them at the Madrigal tonight.
8) Villarreal's chances tonight will largely depend on the form of Giuseppe Rossi. The Italian striker has been a revelation in Europe with 10 goals and three assists to his name.
9) The last time a team recovered from a four-goal deficit in Europe was in 1986 when Real Madrid trashed VfL Borussia Mönchengladbach 4-0 at home after losing 5-1 in the first leg.
10) If Porto do progress into the final, an all-Portuguese final can be guaranteed at Dublin, with the other two semi finalists being Benfica and Braga. It will be the 8th UEFA Cup/Europa League final between two clubs under the same national association.
