Leeds United defender Diego Llorente admits working with manager Marcelo Bielsa has been an experience.
Llorente joined Leeds last summer from Real Sociedad.
On working with Bielsa, he told Marca: "At no time can you relax or not give 100 percent.
"He is very demanding with the ball as well as physically. There is not a single minute of the game in which you cannot contribute, regardless of the position in which you play and whether or not you have the ball.
"What he asks of us is that we always be useful and that we are always helping the team."
