The Brazilian is reportedly the top earner at the Camp Nou alongside Lionel Messi, and Cruyff believes that it is creating tension at the Spanish champions.
"The problem with #FCB is Neymar," Mundo Deportivo quotes the Dutchman as telling reporters in Kuala Lumpur.
"You can't have a 21-year-old earning more than those who've won everything. No-one is God at 21."
Cruyff managed Barcelona between 1988 and 1996, while he also played for the La Liga side for five years in the 1970s.
