Leeds United have enjoyed quite a transformation in recent seasons.
After 16 long years away the Whites finally secured promotion back to the Premier League after a lengthy spell in the wilderness.
Leeds went through their share of hardship during that time but it was the introduction of one man who transformed everything.
Of course we're talking about Marcelo Bielsa.
The Argentine was a game-changing appointment which has certainly served the club well during his two years in charge.
After transforming the culture of the first team squad, Bielsa has made his players physically and mentally superior to many of their opponents, and that looks like it's going to continue into this season.
Seven points from four games at the time of writing has seen Leeds move into the top half of the Premier League - a position that supporters would love to maintain over the course of the season.
While Bielsa is in charge it seem that the club's success will continue, but according to club chairman Andrea Radrizzani, the club aren't scared about the day when he leaves west Yorkshire.
Speaking to La Nacion, Radrizzani said: "I have no doubts that Marcelo is the right person to coach Leeds. I’d like to continue the cycle with him, but I’m not naive either.
“On the one hand, Marcelo is very demanding. For me, that is not a problem, and neither is it for the players, who accept their work culture and see the benefits.
“On the other hand, Marcelo is no longer young. He is 65 years old, and his family is often in Argentina. So I don’t know if he wants to stay and for how long. We analyse it every year and decide it together.
“Obviously, our preference is that it continues. If that is not possible, we will surely have other options in mind.
“But so far we have not considered these options because we believe and hope you can continue with us.”
GIVEMESPORT'S Phil Spencer says...
He's only been at Elland Road for two seasons, but Marcelo Bielsa is already an iconic figure.
While Leeds United have been built on major success during their history, no supporter will ever forget the 16-year period where they struggled outside of the top flight.
Bielsa was the man who transformed the club and got them back into the top tier and that's something that fans will never forget.
When the Argentine does eventually move on from west Yorkshire it will be a sad day for the club.
He may not have won trophies or the Premier League title, but he's done in the last two years is certainly comparable and will be enough to see him regarded as a true club legend in years to come.
