Of his 357 goals for Barca only 137 were not in friendlies. So if you don’t count goals like Pele does, then that puts him at number 6 on Barca’s all-time goal scoring list

Interestingly though Barcelona themselves still list him as ‘the highest goalscorer in the club’s history’

Teams in Spain weren’t professional, that’s why he didn’t score in many games other than professional.
