Argentina played beautiful football under him in 2000-02, Crespo, Kily Gonzales, Claudio Lopez was fantastic interchangable attack with Veron pulling thr strings behind them. Shame they crashed and burned at 2002 world cup with him making some odd selection calls (Batistuta starting ahead of Crespo).
Recovered to win Olympics in 2004 and they should've won Copa America same year v Brazil. Argentina still haven't won a title in the 16 years since he left btw.
Then moved onto Chile who he got into 2010 world cup in style and integrated their golden generation of Alexis, Vidal, Medel so started the building blocks of their success from that point to winning Copa twice between 2015-16.
Bilbao. Everyone on here remembers the europa game v Man. United when they pressed out of their minds home and away. This against a SAF team aswell that was coming off its most successs consistant CL run of a couple of finals. Got to Europa and Copa Del Rey in same final and were unlucky to face peak Guardiola/Messi Barca in one and Atletico Madrid in first stages of Simeone management in the other. And they were dead on their feet which continued the next season.
@DomesticTadpole would give more detalied analysis of his tenure there I'm sure.
Next up Marseille which is biggest club side he's managed in europe. Got them in contention for title for most of the season before they fell away in final weeks. Finished 4th and europa which was o.k but really could've been 2nd.
Lazio. Lasted about 2 days before resigning because they wouldn't sign Enner Valencia.
Would've been interesting him in Serie A given the job Inzaghi has done with the Lazio squad over last 3-4 years.
Then Leeds which has already been covered in depth.
He's a better fit for the fallen giant club rather than one that constantly demands to win trophies but vast majority of players love working under him given the level of coaching so think his ideas would translate well to a top club which has decent patience.
I do actually wonder if Man. City might seriously consider him if this would be Guardiola's last season. I'm sure he'd recommend Bielsa as his replacement if asked but Man. City would probably prefer longer term option like Pochettino.
