Being within the pyramid are probably the only thing they have in common though, and PL would happily get out of that if they could. They don’t even need to enforce each other’s punishments that’s how little the PL care for the EFL.
Man City isn’t over yet so they might if found guilty receive a greater penalty than most think. For me financial breaches are given more ‘lenient’ punishment because it’s harder to quantify how the cheating helped. Playing an eligible player or spying on your opponents is a single game and is easy to award a 3-0 win to them.
If it’s just 1 lone wolf filming on his phone and that video never got back to Southampton coaches then it would be crackers but if they saw the video and didn’t report it then they knew and allowed it, for me they deserve to be kicked out. Don’t care of the video was only them messing around taking shots at the keeper or if it was them doing pens it’s cheating and they knew and covered up.
Nobody knows the extent of the cheating (if any) but if it has happened and Southampton gained even 0.1% of of advantage precedent needs setting and that’s being kicked out, 1 goal changed the whole situation over 210+ minutes a tiny advantage is huge.
