Marcelo Bielsa is a managerial mastermind.
One day he's helping to revamp the parking at Thorpe Arch and the next, he's getting his coaches to study every single set piece in England's top-five leagues.
His methods certainly aren't traditional, but they work incredibly well.
Bielsa's analysis is second to none and consequently, it's not surprising that Leeds have a place back in the Premier League.
The Whites bottled things in remarkable fashion last term but in 2019/20, it was their season, winning the Championship by ten points and finally reaching a place in the promised land.
It took fantastic character for Bielsa and his players to bounce back but it was a testament to the mentality the Argentine and his coaches have installed at Elland Road.
He might be a shy character in front of the media but when put in front of his playing staff, the 65-year-old is anything but quiet.
One thing he isn't usually in charge of is transfers. That's down to Director of Football Victor Orta.
However, you can guarantee the Leeds manager has had a say on their latest target.
Per reports from The Sun, the Yorkshire outfit are looking to sign Liverpool's Harry Wilson this summer.
The winger spent the prior campaign on loan at Bournemouth but is now back at Liverpool and searching for a new club.
Surplus to requirements for Jurgen Klopp, it's thought a fee of £15m will have to be handed to the Reds in order to let him depart.
Leeds face competition from Newcastle and Aston Villa in order to sign the 23-year-old.
GIVEMESPORT'S Matt Dawson says...
Bielsa knows absolutely everything to know about Wilson - that's no understatement either.
When the 13-cap Welshman was on loan at Frank Lampard's Derby County last term, he was one of the players in focus during spy gate.
Leeds sent someone to peer through the fence and watch the Rams train, but funnily enough, Bielsa already knew all too well about the player.
He described the right-winger as "exceptional" in August 2018 and then he became subject of one of the most memorable press conferences in football history.
Following spy gate, Bielsa took to the nation's press in order to explain his methods. In doing so, he showed remarkable levels of detail about Wilson's game.
From basic things like his positions on the pitch to meticulous details like what arm signals Wilson uses for his set-pieces, it was a thorough detailed analysis of the youngster.
If Bielsa scouts the opposition like that then you can guarantee that his recruitment team have a similar form of approach.
Wilson racked up seven goals in the Premier League last term and over 18 months on from spy gate, it appears as though Leeds are still big fans of the player.
