The Whites lost 4-0 on Saturday at home to Tottenham in another embarrassing showing for the club.
Leeds managed an impressive ninth finish in the Premier League last season on their return to the top flight, with Bielsa having taken the club from the depths of the Championship to shining back in the big time.
What's gone wrong for Bielsa at Leeds?
An array of injuries have depleted Bielsa's resources this term and indifferent transfer business has left the club short on options.
This has led to a terrible run of form but not just that, the manner of recent defeats has shone the spotlight on Leeds and Bielsa.
Following a 3-2 win at West Ham on 16 January, Leeds have not won any of their last six league matches, losing five.
The disappointing 1-0 defeat at home to Newcastle United last month has been followed by conceding 20 goals in just five matches. It's a run of results which has peaked in the last few days with a 6-0 hammering at Liverpool in midweek and a 4-0 loss to Tottenham on Saturday lunchtime.
Has Bielsa left Leeds?
talkSPORT are reporting that Bielsa has 'left Leeds' in the wake of the poor run in the Premier League.
The Athletic have also reported that 'nothing come out of Leeds so far and nothing likely to come out this evening now. See what the morning brings'.
Jesse Marsch linked with replacing Bielsa
American coach Jesse Marsch has been linked with replacing Bielsa at Leeds.
Marsch played in the US for D.C. United, Chicago Fire and Chivas USA before moving into management.
He was an assistant for the United States national team and then managed Montreal Impact and New York Red Bulls.
The Princeton graduate then moved to Europe and took over at Red Bull Salzburg from 2019 to 2021 before joining RB Leipzig.
Marsch's list of managerial honours includes two Austrian Bundesliga titles and two Austrian Cups as well as the MLS Coach of the Year award in 2015.
