Farias claimed Argentine managers "have an advantage" over those from other nations, praising Bielsa's achievements but highlighting the fact that he has not been in charge of a club like Real Madrid.
He said: "Be careful, I'm not talking bad about him at all. What happens is that maybe Marcelo has better marketing for being Argentine.
"For me, what he has achieved is wonderful, I hope we can achieve the kind of things that he achieved.
"On the other hand, Bielsa did not manage Real Madrid. In other words, if you have to choose between an Argentine coach and a Venezuelan, obviously they are going to have an advantage, right?"
