Leeds manager Marcelo Bielsa follows 'Spygate' with detailed scouting explanation

When Leeds United manager Marcelo Bielsa called an impromptu press conference on Wednesday afternoon, fans of the Championship leaders were concerned.

Bielsa has been a huge success in his first season at Elland Road -- Leeds are four points clear at the top of the Championship -- but last week's "Spygate" controversy, which saw the club apologise after a member of staff was caught observing a Derby training season ahead of Friday's game between the two teams, has led to an EFL investigation.

So, when the media was called to the Thorp Arch training ground, fears grew that Bielsa was going to resign. But after admitting that "we observed all the rivals we played against and we watched all the training sessions of the opponents before we played against them" and insisting nothing illegal had taken place, the former Argentina manager proceeded to break down exactly how he and his staff scout opponents.

With incredible detail...

The media in attendance settled in for what amounted to a 70-minute seminar.

At one point, Bielsa recounted a story of coaching against Pep Guardiola, which also explains the limits of thorough scouting.

Dossiers on display!

The breakdown went into player-specific detail.

So, why does he do this?

Just in case any Leeds fans were concerned that next opponents Stoke would be an unknown quantity under new manager Nathan Jones...

And from Argentina, Bielsa's old club weighed in.

It remains to be seen what punishment -- if any -- Bielsa receives from the league for last week's events, but the actions with which he followed up on Wednesday were quite remarkable.
