- Spain have beaten Portugal only twice in 54 years (W2, D6, L4).
- This will be the 35th meeting of the sides. Portugal failed to win the first 15 encounters, eventually breaking their duck in 1948. Spain lead the overall head-to-head by 16 wins to six.
- All six of Portugal's victories came on home soil.
- Cristiano Ronaldo has six European Championship goals in total. Only Alan Shearer (seven) and Michel Platini (nine) have scored more in the history of the tournament.
- Spain will set a new record of 11 European Championship finals matches unbeaten if they avoid defeat. Their last loss in the competition was the 1-0 reverse to Portugal at Euro 2004.
- Portugal have hit the woodwork six times at Euro 2012 - including four efforts from Ronaldo.
- Spain have completed 2,623 passes at Euro 2012, more than twice as many as Portugal (1,159).
- The Portuguese have lost four of their five previous semi-finals at major tournaments, and have never won at this stage overseas. Their only win was 2-1 victory against the Netherlands on home soil at Euro 2004.
- The Spanish have kept eight consecutive clean sheets in knock-out games at major tournaments. Goalkeeper Iker Casillas is unbeaten in 780 minutes (13 hours) at this stage since Zinedine Zidane's 90th-minute goal for France at the 2006 World Cup.
