Ronaldo said when Barcelona win it is because of Lionel Messi but when the Spanish giants lose it is down to Ernesto Valverde and Philippe Coutinho as he had a dig at the five-time Ballon d'Or winner.
Barca head coach Valverde was heavily scrutinized after the club's treble hopes ended, while attacker Coutinho was also the target of criticism.
Brazilian great Ronaldo – who played for both Barca and Real Madrid – believes the other players are deserving of more respect in the shadow of superstar Messi.
"Barcelona have a great team, and they have the best player in the world in Messi," Ronaldo said.
"The other day I heard that when they lose, it's because of Valverde, Coutinho... but not Messi.
