Gary Neville believes it is time for Chelsea's owners to have a good long look at themselves after dispensing with their fifth managers in four years.
Liam Rosenior's dismissal came after just 107 days in charge of the club, and puts him on the list alongside Thomas Tuchel, Graham Potter, Mauricio Pochettino and Enzo Maresca.
Chelsea full-back Marc Cucurella spoke earlier this month about how disruptive Maresca's mid-season dismissal had been to the players.
Gary Neville: 'Chelsea owners don't have a clue what they're doing'
Neville, who owns a stake in League Two promotion challengers Salford City and previously had a doomed spell as head coach at Valencia, has been on both sides of the table when it comes to managerial dismissals.
From his perspective, Chelsea's constant chopping and changing
Neville told Sky Sports News: "The way it's happened, it's just not right. I've been there myself, I've sacked a manager after four months and it's a reflection on you when you get it wrong.
"These long contracts though - a six-year contract? It's just bizarre."
He added: "These six-year, eight-year agreements, it's almost laughable from the start. Whether it's for a manager or a player. The owners don't have a clue what they're doing.
"I've made massive mistakes as an owner but sometimes you've got to accept that. I've spoken publicly about the challenges we've had.
"But they're all over the place. I just don't get it, really. You deserve what you get in football and it's a reflection on them, it's not a reflection on a coach who, to be fair, probably shouldn't have been advanced as soon as he was into the role.
"You don't turn down the Chelsea job. I can see why it was appealing but he just has to get on with his coaching career now and put it behind him as quickly as he can. It's a club that is a little bit crazy in its decision-making."
Neville also said: "It's not a reflection on Liam at all. He's lost a lot of football matches in the last few weeks and he'll be disappointed with that.
"But it's time for the owners, sporting directors and players to reflect enormously on their role in what's happened in the last few weeks. Their fans will be absolutely disgusted by the way this has gone."
