#3 Lionel Messi has the most hat-tricks for Barcelona (48)

Lionel Messi is widely known for his stellar goalscoring exploits, particularly in club football for Barcelona.
The Argentine has netted a record 48 hat-tricks in all competitions for the Blaugrana, 36 of them coming in the La Liga. The latter figure is a record tally by any player in the history of the Spanish top flight, two clear of Cristiano Ronaldo.
Messi's 48th and most recent hat-trick for Barcelona came in a La Liga game against Eibar in February last year, with the Argentine netting four times.
Despite netting 38 times in all competitions last season, Messi did not register a single hat-trick.
#2 Most goals for a single club (672)

Lionel Messi has been a prolific goalscorer, scoring a plethora of goals for Barcelona and Argentina. In fact, he is the top goalscorer for both teams.
Messi's tally of 672 goals across competitions for Barcelona is a record by a player for a single club. The Argentine went past the earlier record held by Pele (643) in December last year, with the 34-year-old since scoring almost thirty more times.
However, with the player leaving Barcelona, Messi is all likely to score his 700th goal in club football for another team.
#1 Most goals in a single season (73)

Lionel Messi produced the greatest-ever season in club football in 2011-12 when he netted a staggering 73 times across competitions for the Blaugrana. He also registered an impressive 29 assists that season, both being record tallies.
During that campaign, Messi became the first player in Europe's top five leagues to breach the 50-goal mark. The Argentine also scored 14 times in the Champions League, his most prolific campaign in the continental competition.
However, despite Messi's stellar exploits, Barcelona were beaten to the La Liga title by Real Madrid, while the Blaugrana were eliminated from the Champions League by eventual winners Chelsea in the semi-final. That meant Messi had to be content with only the Copa Del Rey title that season.
The Argentine would go on to score a record 91 goals for club and country during the year, another record tally, which earned him a record fourth-consecutive Ballon d'Or award.
