Lazio president Claudio Lotito says that Marcelo Bielsa spoke like a scientist and believes he had no option but to let the current Leeds United boss leave after disagreements over transfers.
Bielsa was handed the reins at Lazio in the summer of 2016, but his spell lasted only a matter of days before he parted ways with the Serie A side.
The former Marseille boss was unhappy at the club's transfer policy and Lotito has indicated he was unhappy at the players Bielsa wanted to be at Lazio, something which led to a decisive exchange between Lotito, Bielsa and sporting director Igli Tare.
"Bielsa, I sent him away", Lotito told Italian outlet Lalaziosiamonoi.it.
"When I was in France, [sporting director] Tare was callimg me and telling me he had bought some players that the coach wanted, after three minutes they were no good anymore.
"I returned to Formello, with Tare we called the coach and started a certain type of situation.
"Tare spoke to him, he replied as if he were a scientist.
"At one point I was mortified for Igli and I picked up the phone: 'Look Mister, you have to go'.
"Tare was pale."
Bielsa did not return to management until the following year, when he was appointed coach at French side Lille.
He again had a spell to forget, though it lasted longer, and departed Lille towards the end of November.
The Argentine is now in charge at English Championship outfit Leeds.
