• Real Madrid CF's Cristiano Ronaldo and FC Barcelona's Lionel Messi were not among the scorers in either leg of their clubs' respective encounters with Club Atlético de Madrid and Paris Saint-Germain. It is the first time since 2005/06 that both players have been absent from the UEFA Champions League quarter-final scoresheet.
• Barcelona are through to the semi-finals for a record 11th time. Real Madrid and FC Bayern München are the next two most frequent last-four participants with ten and nine qualifications respectively. Juventus will be competing in the semi-finals for the sixth time.
• Madrid and Bayern have both set new club records for successive UEFA Champions League semi-final qualifications, the former going through to the last four for the fifth straight season, the latter extending their run to four. The all-time record is held by Barcelona, who reached six successive semi-finals from 2007/08 to 2012/13.
• Barcelona's win at home to Paris was their eighth in a row in the UEFA Champions League, putting them just two adrift of FC Bayern München and Real Madrid CF, who share the competition record for successive victories, and one behind their own record of nine in a single season.
• Of the 88 semi-finalists in UEFA Champions League history, 26 have been Spanish – the largest contingent from a single nation. It is the fifth successive season that the country has had multiple representation in the last four – a new landmark for the competition.
• It is now a decade since a UEFA Champions League quarter-final went to extra time. The last occasion was the 2004/05 tie between PSV Eindhoven and Olympique Lyonnais, which the Dutch club won on penalties. That remains the only UEFA Champions League quarter-final shoot-out.
• Although there were 11 goals scored in the tie between Bayern and Porto – just two short of the knockout phase record – the aggregate of 19 over the eight games was the lowest in the quarter-finals since 2007/08.
• Only five times in UEFA Champions League history has a team scored five or more goals in the first half, yet Bayern have now done it twice in one season, away to AS Roma last October and now at home to Porto in the quarter-final – the first time the feat has been achieved in the knockout phase.
• Porto's defeat in Munich was their 51st in the competition, extending their own record. It also matched the margin of their heaviest previous loss, 5-0 away to Arsenal FC in the 2009/10 round of 16.
• Jackson Martínez’s consolation goal was the 200th scored by Porto in the UEFA Champions League, making them the ninth club to reach that landmark.
• Real Madrid boss Carlo Ancelotti oversaw his 140th UEFA Champions League match as coach at home to Atlético. He still has 50 games to go, however, to equal the competition record held by Sir Alex Ferguson.
• AS Monaco FC’s Jérémy Toulalan made his 50th UEFA Champions League appearance in the 0-0 draw at home to Juventus. The France international has also played in the competition for FC Nantes, Olympique Lyonnais and Málaga CF.
