Interpreting user request

I need to understand the user’s request, which translates from Chinese to something like "Barca Messi goal breaking records Champions League historic moments." It looks like they’re asking for highlights or a description of Messi's record-breaking goals in the Champions League, particularly with Barcelona. I'm thinking of compiling key moments, like Messi being the youngest scorer to 100 goals and his record hat-tricks, including 5 goals vs. Leverkusen. His record for most goals for a single club in UCL stands out too!Clarifying Messi’s records

Okay, Messi scored 120 goals for Barcelona in the Champions League by 2021, which is the record for the most goals for a single club. As of now, he's with PSG and Inter Miami, so no longer in the UCL. Overall, Messi totals 129 UCL goals, with 4 of those from his time at PSG. He became the second player to hit 100 UCL goals on March 14, 2018, in a match against Chelsea, having scored 2 goals in that game. Cristiano reached his 100 goals earlier in 2017.Reviewing UCL records

So, Messi became the second player to reach 100 UCL goals, but that's not a record-breaking achievement.

Now, looking at other records: Ronaldo holds the record for the most goals in a single UCL season with 17 in 2013/14, while Messi scored 14 back in 2011/12. For most hat-tricks, both Messi and Ronaldo are tied at 8 as of 2023; Messi had previously held the record with 5 hat-tricks until Ronaldo matched or overtook him. Also, Messi famously scored five goals in one UCL match against Bayer Leverkusen on March 7, 2012.Identifying record moments in UCL

Messi set a historic record as the first player in the Champions League era to score five goals in a single match; later, Erling Haaland matched this for Man City in 2023 and Luiz Adriano did it in 2014 for Shakhtar.

For the fastest 100 Champions League goals, Messi achieved this in 123 games compared to Ronaldo's 144 games, making Messi the fastest by appearances when he scored against Chelsea.

Ronaldo holds the record for most group stage goals in a season with 11 in 2015/16, while Messi had 10 in 2016/17, which isn't a record.Highlighting Messi’s record moments

Messi scored in 15 consecutive Champions League seasons by the 2019/20 season, though Cristiano leads with 17. He also holds records like being the youngest to reach 50 UCL goals, achieving this at 24 years and 284 days in November 2012.

Key historic moments for Messi in the Champions League include:

• 2009 Final vs. Manchester United: Scored a header for a 2-0 lead.
• 2012 vs. Bayer Leverkusen: First player to score five in a single UCL match (7-1).
• 2014 vs. APOEL: Scored a hat-trick to surpass Raul for the all-time top scorer (74 goals).
• 2018 vs. Chelsea: Fastest player to 100 UCL goals.
• 2018 vs PSV: Achieved his eighth UCL hat-trick, surpassing Ronaldo's record.
