After Saturday's loss to Spurs, the future of the Leeds United boss is in serious danger.
The popular Argentine coach was already under pressure.
The home defeat by Spurs has made the situation even more precarious.
Senior figures at Elland Road believed that the 66-year-old would leave at the end of the season.
They have to decide whether to act now or wait.
Jesse Marsch is a former coach of RB Leipzig. There are other potential candidates, including former Barcelona boss Ernesto Valverde, who is currently out of work.
Carlos Corberan was a boss who worked for Bielsa. There are doubts as to whether he would be interested in returning to Yorkshire in the middle of the season.
After guiding the club back to the top flight in 2020 after a 16-year absence, his status as a hero at the club is secure.
Injuries have hampered the team this season.
The club's form has collapsed since a win at West Ham last month, as key men KalvinPhillips and Patrick Bamford have been absent for most of the season.
They have collected a single point from their last six games. They have allowed 20 goals in the last five weeks.
The result today means they are two points ahead of third-bottomBurnley, who have a far superior goal difference and two matches in hand.
In their last three league games, Leeds have faced Manchester United, title-chasingLiverpool and Spurs.
The manner of all three defeats raises serious questions about the approach of Bielsa.
They have conceded 60 goals this season, but only three of them have come in February, when they conceded six at Anfield and four at home to both United and Spurs.
They have conceded more goals than any other side. Half as many have been let in by Clarets, who are currently in the bottom half of the table.
The team is the second in the history of the league to concede three or more goals in five consecutive matches.
The Argentine insisted that he had no intention of changing the style of the team after Wednesday's loss to the team coached by the German.
He said that it was not only a problem of how we defend, but with the total functioning of the team.
We need to impose what we are attempting and we are not doing it.
Paul Robinson is a former goalkeeper for the club and he says that the club's survival hopes could be in danger if they replace Bielsa at this stage of the season.
If you make a change now, it is too big, he said.
The nucleus of this squad is a Championship squad. Is it possible for another manager to get more effort, enthusiasm and application from these players?
When he leaves, he will be able to choose which corner of the ground he wants his statue on, but at the moment it is not looking good.
Rio Ferdinand said that a change of tactics was necessary.
He said that they will keep sliding down the table with these tactics. Something has to change.
They can either sack the manager or stick with the man who pulled them out of the Championship.
He is an incredible manager but the best managers always adapt.
They are in the bottom half of the league. The spine of the team has been out for a long time, but they are exciting to watch. You have to adapt without them. You have to adapt without them.
Insanity is doing the same thing over and over and expecting different results. I am starting to doubt the methods. I hope it can be kept up.
Yes, but he has to go. I'm hiding behind the sofa. These tactics do not work.
Mark is afraid of Leeds. They are watching a group of teams with games in hand. As entertaining as they were last season, it caught up with them. They will be taken down.
In the first season, the unusual style catches people out, but in the second season, they are found out. It's hard to see them staying up.
The same people who celebrated the excitement of the last season of the premier league are moaning about the current season. We have never seen anything as crazy as this team in the league, I pray they stay at 17th.
