Former Celtic manager Neil Lennon says the abuse faced by managers of Celtic and Rangers will "no question, absolutely" put coaches off coming to Glasgow to take charge of either side.
Lennon, now boss of Championship side Dunfermline Athletic, also reckons the "scrutiny" and "vitriol" in management has "got worse" in recent years.
Rangers are currently recruiting for a new head coach to replace Russell Martin, who endured sustained pressure as well as protests from fans before being sacked earlier this month.
"I think it has got worse in Glasgow," Lennon, who was boss at Parkhead twice, said on BBC Scotland's Saturday Show.
"The scrutiny of the individual and the analysis – Brendan [Rodgers at Celtic] at the moment, and whoever will take over at Rangers, it's really claustrophobic."
On Martin being escorted off the pitch after his side's 1-1 draw with Falkirk before leaving in the back of a car after fans blocked the team bus, Lennon added: "I think it's really sad."
Martin was sacked as Rangers head coach after 17 games. Steven Gerrard turned down the chance to return to Ibrox as box, while Danny Rohl has also pulled out the running.
Lennon has suggested that potential new head coaches, for either side of the Old Firm, would now think twice about stepping into the role.
"[Incoming managers will be] saying 'I don't need that', yeah, no question," he said. "Absolutely. Without a doubt.
"Across Europe, you see fans demonstrating outside training grounds, it didn't used to be like that in Scotland.
"It's become really prevalent over the last three or four years."
He added: "The scrutiny, the vitriol at times you just have to look at what happened to Russell Martin. It was really poor. He didn't get the results the job demanded but the way he was treated by some aspects of the media and social media was awful."
These comments come after Rodgers suggested the difference in pressure between Premier League sides and the Old Firm sides is significant.
"People are angry, the world is angry, but it's not nice to see, they are human beings at the end of the day," said Lennon.
"If they aren't good enough, fine, but there's no need for the personal attacks and constant personal abuse.
"We all get the banter, but there is other stuff that is really poisonous and that needs to get eradicated.
"I don't know how if we get rid of it but it's not a good look for Glasgow, for Glasgow football."
