Opinion was divided in football circles when Bielsa was appointed Leeds boss in the summer.
For those aware of his pedigree and backstory it was seen as one of the managerial coups of recent years.
Especially given Leeds were in the Championship and the Argentine's reputation as one of the most brilliant and maverick managers of a generation.
Others saw it as a huge risk because of Bielsa's awkward nature and having walked out on Lazio just two days into the job.
The fact is the Argentine is widely adored and even hailed as the world's best coach by the likes of Pep Guardiola and Mauricio Pochettino.
And it is not without good reason as Leeds fans will already testify.
Leeds are riding high at the top of the Championship with 18 points from their opening nine games and doing it in some style.
Supporters have been here before with strong starts fading away an all too familiar tale.
Leeds are hoping he can be the man to finally get the sleeping giant back in the big time.
It is a far cry from Bielsa's last job, where he was sacked by French side Lille having first been suspended by the club following a poor run of results.
Despite Saturday's shock 2-1 home defeat to Birmingham, this time there seems to be more substance to the momentum building at Elland Road.
But surely proof if it was needed that Bielsa is finally the right man to take Leeds forward comes in new comments from his old boss at Lille, the owner Gerard Lopez.
Speaking on French TV show Téléfoot, Lopez was critical of Bielsa because he WANTED to build the club up using young talent.
“He took a big risk," Lopez told Téléfoot.
“There was clearly not enough experience in the squad.
"The coach took a big risk with young players, but it was under my responsibility. Now with players like José Fonte, that makes a difference. Do I regret it (sacking Bielsa)? Not at all.”
Building a club up playing exciting football using young, homegrown players is exactly what most football fans want.
So it seems Lille's loss is very much Leeds' gain.
Lopez says he does not regret letting Bielsa go but his Leeds counterpart Andrea Radrizzani certainly doesn't regret appointing him on the evidence so far.
If Bielsa repeats that blueprint at Elland Road, it will put the club in great stead for a bright future.
