The Argentine continues to rewrite the club's history books as his strike on Saturday means he has now beaten the Brazil legend's record of 34 goals during the 1996-97 campaign
The Argentine's first-half strike against the islanders means he has now scored 35 times in the league this term, overtaking Ronaldo's previous high of 34 during the 1996-97 campaign for the Blaugrana.
Messi equalled Ronaldo's overall mark in 2009-10, and last season scored 53 goals in all competitions, surpassing the Brazilian's haul of 47 in the process.
The 24-year-old is now on course to beat Real Madrid attacker Cristiano Ronaldo's return of 40 goals last term, currently the highest by any player in a Liga campaign.
It has been a year to remember for Messi, who also became Barcelona's leading scorer of all time earlier this week and the first-ever player to score five goals in one Champions League match as he netted a quintuple against Bayer Leverkusen recently.
