Leeds United boss Marcelo Bielsa reveals full extent of spying tactics

Leeds United boss Marcelo Bielsa has revealed he is ready to co-operate fully with the Football League's spying investigation.
Bielsa is taking full responsibility for sending a member of his backroom staff to watch over Derby County during a training session ahead of Leeds' recent 2-0 win over the Rams.
The Argentine called a lengthy press briefing at the club's Thorp Arch training ground on Wednesday to explain in detail how he prepares his team for ALL games.
He made it clear that Derby weren't the only opponents who they have seen train behind closed doors this season.
