Sheffield United boss Paul Heckingbottom says the Premier League cannot stop with Everton over penalising clubs for breaching spending rules.
Everton were hit with a ten point penalty last week for breaking profit and sustainability rules.
"I think it's opened the door to other sanctions, we can't just have one team punished, we need more if there's been breaches," Heckingbottom said referring to last season's transfer embargo.
"We suffered last season from that and I think, me being a football fan I think it's only right. The rules are out there for a reason, otherwise what's the point.
"From Everton's point of view, they're going to feel hard done to because they are the first and it's the biggest punishment we've had in the Premier League so that will only be seen as justifiable if others follow suit, with bigger punishments potentially, so it's opened up all sorts."
He added, "From a football point of view, I've been impressed with Everton this season," he told Sky Sports. "I think they should have had more points than what they've had anyway so whilst it initially knocks them down into where they are, they've shown more than enough for me to show that they are going to be fighting and be more than capable of working their way out of it. We just hope that we finish above them.
