Norwich City demand answers from the EFL over Marcelo Bielsa ‘spy-gate’ controversy at Leeds United
Something is going to happen because of the amount of clubs involved. The EFL has 22 clubs being spied on, even if the spying made no difference at all to any games, the other teams have opportunity to unsettle Leeds and try to gain advantage.
Say you're Sheffield United or West Brom, itching to get promoted and here's an opportunity to unsettle the club above you in the league, they're not going to politely ruffle Bielsas hair and laugh about him being called loco.
I don't know what penalties will or can be enforced, points deduction seems unlikely, but you can guarantee that the other clubs will try to make life as uncomfortable as possible for Leeds.
I'm glad City is pushing the EFL, we knew what Leeds would do of it was someone else spying on them.
