Let's face it, Lionel Messi and Cristiano Ronaldo are known to break records for fun and both these legends have reached at a stage in their respective incredible careers that with every goal or appearance, they tend to break one record or another.
However, here are eight UEFA Champions League records that both these legendary footballers are yet to break in their respective glorious careers....
8. Goals in European Cup Finals
Most goals in European Cup finals: 7 – Alfredo Di Stefano, Ferenc Puskas (both from Real Madrid)
Goals in most European Cup finals: 5 – Alfredo Di Stefano (for Real Madrid in 1956, 1957, 1958. 1959, 1960)
Most goals in a single European Cup final: 4 – Ferenc Puskas (Real Madrid, 1960)
FC Barcelona legend Messi has scored only two final goals (in 2009 and 2011) while current Juventus hitman Ronaldo has four (one apiece in 2008 and 2014, and two in 2017) but both are still shy of the record of seven goals in European finals by Real Madrid legends Di Stefano and Puskas.
Ronaldo has also made six final appearances, which is one less than Alfredo Di Stefano and two less than record holders Francisco Gento (Real Madrid) and Paolo Maldini (AC Milan).
7. UEFA Competition Appearances
Most appearances in the UEFA Champions League/European Cup (including qualifying): 181 – Iker Casillas
Most appearances in UEFA club competitions (including qualifying): 188 – Iker Casillas
Ronaldo (129) and Messi (115) still have quite a long way to go when it comes to overtaking bonafide footballing legend Iker Casillas' appearance record in UEFA club tournaments.
Messi is joint 24th in the all-time UEFA competition appearance rankings with 139; whereas Ronaldo, who is two years and 139 days older than Messi, ranks fifth with 170 appearances.
6. Champions League triumphs and goals scored with different sides
Cristiano Ronaldo has a unique record of winning the UEFA Champions League with two different clubs, Manchester United and Real Madrid, however he needs to win the 'Big Ears' once more to equal Clarence Seedorf's record of winning the trophy for three different clubs.
Zlatan Ibrahimovic's record looks even more impossible for Messi and Ronaldo in order to score for six different clubs across Europe. All of Messi's strikes to date have come for Barcelona, while Ronaldo has only played for United, Real Madrid and Juventus in the UEFA Champions League.
Final wins with the most teams in the UEFA Champions League: 3 – Clarence Seedorf (Ajax 1995, Real Madrid 1998, Milan 2003, 2007)
Player who have scored for the most teams in the UEFA Champions League: 6 – Zlatan Ibrahimovic (Ajax, Juventus, Internazionale, Barcelona, Milan, Paris Saint-Germain)
5. Oldest goalscorer
Both players are also chasing the record for being the oldest goalscorers in European competitions as below:
UEFA Champions League final: Paolo Maldini (36 years 333 days) – Milan v Liverpool (25/05/2005)
UEFA Champions League, group stage to final: Francesco Totti (38 years 59 days) – CSKA Moskva v Roma (25/11/2014)
European Cup: Manfred Burgsmüller (38 years 293 days) – Werder Bremen v Dynamo Berlin (11/10/1988)
4. Fastest goal
Fastest UEFA Champions League goal: Roy Makaay (10.12 seconds) – Bayern München v Real Madrid (07/03/2007)
Fastest UEFA Champions League final goal: Paolo Maldini (53 seconds) – Milan v Liverpool (25/05/2005)
All goals scored in UEFA competitions' finals by both Ronaldo and Messi barring one from the Portuguese hitman, have come in the second half of games.
Cristiano Ronaldo's round of 16 treble against Atletico Madrid last season drew him level with Messi's all-time record of eight hat-tricks in Europe's top club competitions.
However, neither players have yet managed to score the fastest hat-trick in the history of the Champions League with Bafetimbi Gomis' crazy quick treble in seven minutes against Dinamo still the fastest hat-trick in the competition's history.
Messi's fastest hat-trick came in 22 minutes against Arsenal in 2010 whereas Ronaldo's fastest treble came in 12 minutes against Malmo.
2. Goals in most successive Champions League seasons
Messi scored in his 14th successive UEFA Champions League campaign in 2018/19 to equal Raul's record for goals in the most successive UCL seasons.
Ronaldo too has scored in his last 14 Champions League campaigns, after having failed to register in his first two seasons, both with Manchester United.
Both players can match Ryan Giggs's record tally of scoring in 16 successive Champions League campaigns when they reach the year 2020/21.
1. Most goals in a single Champions League campaign
This incredible record is set by none other than Colombian football legend Radamel Falcao. Falcao scored a total of 18 goals for FC Porto in the UEFA Europa League's 2010/11 campaign. He scored one goal in qualifying rounds and 17 in the competition.
Messi's best goalscoring year came in 2011/12 when he ended the European season with 14 strikes, while Ronaldo set a European Cup/UEFA Champions League record with 17 in 2013/14.
