Bielsa back in England seeking end to boom-bust pattern after Luis Suárez attack | Jonathan Wilson

The Uruguay coach, who had such an impact at Leeds, needs a result at Wembley on Friday after a downturn for the South American side

The pattern is not unfamiliar. Marcelo Bielsa arrives. The force of his personality, the radicalism of his ideas, his charismatic eccentricity, elevates everybody. Results are good, performances intoxicating. The football is not merely successful but comes to be regarded almost as a moral good: playing the right way for a manager who projects a profound sense of integrity.

Gradually the picture changes. Fatigue sets in. Players weary of their manager’s obsessive nature. Pundits and fans begin to wonder if everything has to be quite so relentless all the time. Bielsa’s quirks come to be regarded less with affection than with aggravation. Levels drop, Bielsa leaves.
