3) Sporting Lisbon
One of the ‘Tres Grandes’ or the Big Three in Portuguese football, Sporting Lisbon has consistently failed to match the European exploits of the other giants of the league, Benfica and Porto. While the latter duo have numerous European titles in their cabinet, Sporting's only European honour is a Cup Winners Cup victory in 1963-64 which they achieved via a 1-0 victory over MTK Budapest in the final.
Since then Sporting have regularly fallen short in European competitions, but reached the final of the UEFA Cup in 2005 where they lost 3-1 to CSKA Moscow despite playing at their home ground. Sporting do have multiple semi-final appearances in the UEFA Cup/Europa League, but could never win it all.
The 18 time Primeira Liga Champions’ first appearance at the new UEFA Champions league knock-out stages was in the 2008-09 season where they were thrashed 12-1 on aggregate by Bayern Munich.
