Marcelo Bielsa has cast doubt over his future at Leeds United.
Bielsa insists he signed a new one-year contract extension only because he believed he could improve upon last year's encouraging ninth place after guiding the Yorkshire club back to the Premier League.
So his frank admission that his methods aren't working will set alarm bells ringing at Elland Road.
Bielsa said: “I focus on the performance of the team, and the weaknesses that we have shown were precisely the ones I had worked on to elevate us from last season.
“So when I made the decision to work here for one more year, it was because I had the conviction that the team could be better.
“That depended on some decisions and developments. I wanted the developments to help the team to grow – but I haven't achieved it."
