UEFA Champions League: Did you know?
• In 2012/13, Chelsea became the first defending champions to fail to get through a group stage since the UEFA Champions League began. (This record, like the others, includes the seasons between 1999/2000 and 2002/03 that featured a second group stage). In 1992/93, Barcelona were the reigning European Champion Clubs' Cup holders and lost 4-3 on aggregate in the second round to CSKA Moskva.
• In 2016/17 Real Madrid became the first team to successfully defend the UEFA Champions League trophy, with AC Milan (1989, 1990) the previous club to win consecutive European Cups. Milan (1994, 1995), Ajax (1995, 1996), Juventus (1996, 1997) and Manchester United (2008, 2009) have all returned to the UEFA Champions League final as holders only to lose.
• Real Madrid then made it three wins in a row in 2017/18, becoming the fourth club to win three or more successive titles in European Cup history, and the first to do it twice.
• Only two teams have ever won the UEFA Champions League on home soil: Borussia Dortmund (1997, final in Munich) and Juventus (1996, final in Rome), while Manchester United lost the 2011 final in London and 12 months later Bayern were beaten in the showpiece in their own stadium, the Fußball Arena München.
• Barcelona have finished as group winners on 20 occasions, four more than Real Madrid and five more than Bayern München and Manchester United. Barça also hold the record for the most unbeaten group stage campaigns with 12, four more than Real Madrid.
• Bayern München (2 April 2013 to 27 November 2013) and Real Madrid (23 April 2014 to 18 February 2015) jointly hold the record for successive wins in the UEFA Champions League proper with ten. Bayern surpassed the previous mark of nine, set by Barcelona between 18 September 2002 and 18 February 2003.
• Six teams have recorded six successive victories in a UEFA Champions League group stage: Milan (1992/93), Paris Saint-Germain (1994/95), Spartak Moskva (1995/96), Barcelona (2002/03, first group stage) and Real Madrid (2011/12 and 2014/15).
• Twenty-one teams have gone through a UEFA Champions League group stage without picking up a single point, most recently AEK Athens in 2018/19.
• In 2017/18, Paris Saint-Germain set a new group stage record by scoring 25 goals, with Liverpool (23) also eclipsing the old mark of 21 set by Borussia Dortmund in 2016/17. Manchester United (1998/99), Barcelona (2011/12, 2016/17) and Real Madrid (2013/14) all managed 20.
• Only Deportivo La Coruña (2004/05), Maccabi Haifa (2009/10) and Dinamo Zagreb (2016/17) have failed to score in a group stage.
• BATE Borisov conceded 24 goals in 2014/15, a new group stage record which was matched by Legia Warszawa in 2016/17. The previous mark, 22, was held by Dinamo Zagreb (2011/12) and Nordsjælland (2012/13); Malmö shipped 21 in 2015/16.
• No team has ever gone through a UEFA Champions League group stage without conceding a goal. Milan (1992/93), Ajax (1995/96), Juventus (1996/97 and 2004/05), Chelsea (2005/06), Liverpool (2005/06), Villarreal (2005/06), Manchester United (2010/11), Monaco (2014/15), Paris Saint-Germain (2015/16) and Barcelona (2017/18) all let in just one.
• Matchday six of the 2013/14 marked FCSB's 23rd successive game in the competition without a victory, surpassing the previous record of 22 set by Spartak Moskva between December 2000 and November 2006.
• Anderlecht hold the unwanted record for successive defeats in the competition, group stage to final, having lost 12 in a row between December 2003 and November 2005. Dinamo Zagreb are next with 11 consecutive losses on two occasions, from September 2011 to November 2012 and ongoing since September 2015.
• The lowest total for a team qualifying from the group stage is six points: Zenit in 2013/14 and Roma in 2015/16. Since three points for a win was introduced in 1995/96, nine teams have made it through with seven points: Legia Warszawa (1995/96), Dynamo Kyiv (1999/2000), Liverpool (2001/02, second group stage), in 2002/03 Lokomotiv Moskva (first group stage) and eventual finalists Juventus (second group stage), Rangers and Werder Bremen (2005/06), Galatasaray (2013/14) and Basel (2014/15).
• Napoli failed to qualify from their group with 12 points in 2013/14, the highest total of any team not to reach the next stage when the top two in each section progressed. Dynamo Kyiv (1999/2000, second group stage), Borussia Dortmund (2002/03, second group stage), PSV Eindhoven (2003/04), Olympiacos and Dynamo Kyiv (both 2004/05), Werder Bremen (2006/07), Manchester City (2011/12), Chelsea and Cluj (both 2012/13), Benfica (2013/14) and Porto (2015/16) all missed out with ten points.
• Lionel Messi became the first player to score five goals in a match in Barcelona's 7-1 win against Bayer Leverkusen on 7 March 2012, a feat matched by Shakhtar Donetsk's Luiz Adriano at BATE Borisov on 21 October 2014. Eleven more players, also including Messi, have scored four times in a game, most recently Cristiano Ronaldo for Real Madrid on matchday six in 2015/16.
• Cristiano Ronaldo set a new record for a UEFA Champions League group stage with 11 goals in 2015/16, eclipsing his own mark of nine in 2013/14, which Luiz Adriano matched in 2014/15 and Ronaldo himself equalled in 2017/18. Lionel Messi got ten goals in 2016/17; Zlatan Ibrahimović (2013/14), Ruud van Nistelrooy (2004/05), Filippo Inzaghi, Hernán Crespo (both 2002/03) and Robert Lewandowski (2018/19) managed eight.
• Messi's hat-trick against PSV Eindhoven on matchday one of the 2018/19 competition was his eighth in the competition, a mark Ronaldo matched against Atlético Madrid in that season's round of 16 second leg.
