Ex-Liverpool attacker Maxi Rodriguez has hit out at criticism from Marcelo Bielsa's brother.
Rodriguez is still playing for Bielsa's favourite side back in Argentina, Newell's Old Boys.
Bielsa's brother Rafael is a politician and recently criticised Rodriguez and the club.
Rodriguez, 38, took exception to this, saying that the Leeds United boss is the only Bielsa who maters.
He told 442 Argentina: "It is always easier to destroy than to build and what he is doing is that. At this moment it is useless.
"I invite him again to come and add and collaborate with the club because it [Bielsa] is a very important last name, especially here the important one is Marcelo, it is not him."
Marcelo Bielsa won league titles with Newell's back in 1991 and 1992.
He has retained an affection with the club ever since, pledging £3 million of his own money to the club to fund a new training centre, the Yorkshire Evening Post reported last year.
The club's current campaign is not going so well, prompting the row about how to make things better.
Newell's sit in 15th place of 26 teams, 25 games into the season. How they could do with the Leeds boss in charge now. One day perhaps.
