After equalling his fellow Brazilian's tally during last month's 4-0 Liga victory at Eibar, Neymar's goal after 40 minutes moved him on to 95 for the Catalans.
Ronaldinho is a Barca icon, having won two La Liga titles and the Champions League in a five-year spell with the club between 2003 and 2008, and was recently named a sporting ambassador for the Catalan club.
But aged just 24 and with a contract until 2021, Neymar will expect to continue climbing a Barca goalscoring list that still has legendary names like Samuel Eto'o, Rivaldo and Patrick Kluivert above him.
Leader Lionel Messi represents an unrealistic target, though – he has an astonishing 484 club goals and is still going strong.
Neymar joined Barca from Santos in 2013, after winning the Copa Libertadores with his boyhood club and breaking into the Brazil national team while still a teenager.
