Unless there are genuine signs of a turnaround of a turnaround against Tottenham I think he needs to go
1 Inflexible approach - our players squad are not good enough to carry off how he wants us to play
2 Regularly concede goals which is going to get us relegated
3 The players must be questioning Bielsa Ball when it clearly is not working and losing faith
Not sure who could be brought in, but unless Bielsa is prepared to change tactics we are going to be relegated.
Hope I am wrong about all the above
