The English Football League confirmed 11 Championship clubs have made contact regarding Leeds United after its manager Marcelo Bielsa admitted to sending spies to watch training sessions of every team his side have faced this season.
Bielsa made a full and frank confession after an employee of the club was caught outside Derby County's training ground in the week leading up to Leeds' 2-0 victory over the Rams.The EFL launched a formal investigation after Derby lodged a complaint, and more unnamed clubs have since made their views known.
"The EFL has received a communication on behalf of a number of Championship clubs in regard to the current matter involving Leeds United," a statement from the EFL read. "The request attributed to 11 clubs will be considered as part of the current investigation that has commenced."
Bristol City owner Steve Lansdown said Leeds should be docked points.
"The only thing that makes sense if I'm honest is a points deduction," Lansdown told BBC Points West. "They ought to seriously consider it but I don't think that will happen as I don't think the EFL will be strong enough to do something like that.
"A fine would go some way towards showing it's not acceptable. Whatever happens we mustn't condone it.
"If he'd asked to send someone to watch our training we would have said no. And every other football club would say no. So why does he think it's acceptable to do it?
"However great a coach he is, it's the wrong thing to do. Poking around and skulking around a training ground is not part of the game."
