Leeds boss' spell at Lille was short lived.
Leeds United are benefitting from Marcelo Bielsa's management and almost won promotion last season.
Bielsa was available after his spell in charge of Lille ended in disaster.
The Argentine lasted just a matter of months, departing bitterly amid poor results.
But it wasn't all bad, with Lille just profiting from one of his best decisions.
The Leeds boss' signed Thiago Mendes for Lille in July 2017 from Brazilian side Sao Paolo.
Lille paid a bargain fee of just £7 million for his signature.
It puts a biggest spin on Bielsa's biggest failure in club management, showing that he did make some smart decisions even if results did not work out.
The big shame for Leeds is that Bielsa is not currently being given funds to replicate his Mendes success.
Leeds are relying on loan deals this summer, which could hamper their chances of winning promotion.
