Her er det Bielsa har måttet gå gjennom denne sesongen:
Kemar Roofe is out and Leeds' long injury list grows ahead of Derby second leg

Kemar Roofe returned and all was right in Leeds United's world. This season should have taught them that it would have been turned upside down sooner rather than later.
Ahead of their biggest game in 15 years, the second leg of their play-off semi-final against , Leeds' injury crisis has not abated.
They have been without Roofe, their top scorer, for large chunks of this season already. He managed two games and a crucial goal this time around before succumbing to a calf problem.

But it is not just Roofe who has been in and out of action this campaign. Leeds have only had their two main strikers — Patrick Bamford being the other — available at the same time for about two months in total.
Bamford will start on Wednesday night having somewhat dealt with the knee problems that took him out for three months before Christmas and two months after.
While he has managed 10 goals, he comes into the second leg on the back of a two game absence after picking up a ban for deception of the referee.
Leeds have also generally performed better with Roofe playing instead of Bamford, primarily due to his style meshing better with Marcelo Bielsa's philosophy. Roofe has four goals in three games against Derby this season alone.

There are injury problems away from the forward line too. Against Derby, Leeds could have half of their first-choice defence missing.
Pontus Jansson is a doubt. Left-back Barry Douglas will not play again this season. Gjanni Alioski, recovering from a knee injury, has a small chance of making it if they reach Wembley — but not on Wednesday.
Third-choice left-back Leif Davis is injured, which means Stuart Dallas will retain his place there. It is worth noting the Northern Irishman is a right winger.
Further forward, Adam Forshaw was also ruled out for the campaign by Bielsa after picking up an injury against Derby. Tyler Roberts, who has impressed in central midfield since the turn of the year, is also not going to kick a ball again this season.

That means Jamie Shackleton, 19 years old and with the face and build of someone half that age, will continue on in midfield after impressing there off the bench in the first leg.
It is worth noting that Shackleton deserves an opportunity and has been earmarked for years as the next star from the Leeds production line.
The bench will be similarly young. There'll be another academy name on there on Wednesday to add to Bailey Peacock-Farrell, Jack Clarke, Pascal Struijk, Robbie Gotts and Mateusz Bogusz, who were joined by relatively senior figure Izzy Brown on Saturday.
Brown, of course, is on loan from Chelsea and is at the grand old age of 22. He has made one appearance for Leeds. The bench on Saturday had an average age of 19.

It would be easy enough to blame this on Bielsa's famed fatigue but the man himself had a point to make on Monday.
'You've heard that my teams usually arrive at this point of the season tired from a physical and mental point of view,' he said. 'The game against Derby [on Saturday] was the game where we ran most in the whole season.'
Leeds have probably been a combination of unfortunate and overly demanding this season. There have been plenty of impact injuries and plenty of muscular problems.
Every single member of the first-team, barring the ever-present Mateusz Klich, Kalvin Phillips and goalkeeper Kiko Casilla, has suffered an injury at some point.

LEEDS' ABSENTEES
OUT: Kemar Roofe, Tyler Roberts, Adam Forshaw, Gjanni Alioski, Barry Douglas, Leif Davis
DOUBTS: Pontus Jansson
What Bielsa demands every day on the training ground is 100 per cent commitment. That surely has a part to play in the number of problems they've picked up, rather than simple fatigue.
Training with their high-intensity 'Murderball' — a full-blooded match — session three days ahead of a game surely does not help, as much as the players enjoy it.
As Jansson said in February: 'The worst thing for us is that you can sometimes feel tired before the match because we work so intensely. He (Bielsa) has a philosophy that if you are tired you should train even harder to make it better. He has that philosophy and won't change.
'We thought he would understand after a while that the league is a bit tougher and that you sometimes have to be a little smarter about how to train but he has not changed anything, just driven on almost even harder. He has his philosophy and does not let it go.'

That might be the trade-off, though, for a team who finished 13th last campaign to be in contention at this stage with minimal investment.
They have beneF***ed from their fitness, scoring eight goals after the 90th minutes. That saw them pick up two late wins over Christmas, including a 3-2 win against Blackburn in which they trailed 2-1 in the 90th minute.
The incredible thing is that Leeds did look to be near their best on Saturday. The goal, courtesy of a free-flowing move between Dallas, Jack Harrison and Roofe, was superb.

Neither Dallas nor Harrison were anywhere near first-choice when the two teams clashed in August.
This is the triumph of Bielsa's coaching. Whoever the personnel are, Leeds still perform. Whether it is a kid from the academy or a senior star who has been out of favour, they tend to just slot in when an injury hits.
Derby have reason to believe on Wednesday night, but until now, whether or not the treatment room at their Thorp Arch base resembles a field hospital at the Somme, Leeds have just about managed.
Roofe-less or not, Leeds still have the capacity to be ruthless.
