The Argentine has performed a transformative job since he took over at Leeds United in 2018, revitalising the club on and off the pitch.
Guiding the Whites back to the Premier League after a 16-year absence, while also helping to engender an optimism that had been missing for far too long at Elland Road, El Loco is, undeniably, a hero.
But for all of the material success that has come, the true hallmark of this Bielsa side is the entertainment value that they offer.
Whether it be relentless attacking displays that bully teams into submission, or a never-say-die attitude that leads to late drama time and time again, there are few sides in the English game who can match Leeds when it comes to getting pulses racing.
The boss celebrated his 100th league game in charge against Crystal Palace on Saturday, and we’ve counted down the 13 most thrilling matches from his first century.
13. Leeds United 5-4 Birmingham City, December 2019
Where do you even begin with this one? A result ripped straight from the pages of a comic book, Leeds had been 2-0 up before their hosts pegged them back to 2-2 with half an hour to go. Luke Ayling gave the Whites the advantage once more, but a flurry of four goals after the 83rd minute turned this one into an instant classic. City equalised twice in the last ten minutes, including a 91st minute strike from Lukas Jutkiewicz, but Bielsa's men still had one more ace up their sleeve and a 95th minute own goal sealed the victory. The dictionary definition of a thriller. (Photo by George Wood/Getty Images) Photo: George Wood
