David Moyes has told Newcastle owner Mike Ashley he should follow the example of Everton if he wants to make the Magpies successful.
It is nearly seven years since Moyes took over at Goodison Park and in that time the Magpies have had 10 different bosses, including caretaker managers. Moyes, who takes his Everton side to St James' Park on Sunday, believes that is the main reason why they have struggled to establish themselves as a top-six club.
"Newcastle have always spent and supported their managers but in truth the lack of stability has probably cost them over the years," said the Everton boss. "I use Everton as an example. The board have kept things steady and the group of players has been consistent."
He added: "Players come in and out like anywhere else but fundamentally we have tried to keep the core correct.
"If you keep chopping and changing I don't think, for the long-term future of any football club, it is the way to do it."
As if Newcastle needed any further disruption, they are currently without manager Joe Kinnear who has been ordered to take two months off after heart bypass surgery.
Moyes passed on his best wishes to the 62-year-old, whose absence he felt could even help to galvanise the team.
"We hope Joe Kinnear is well and recovers," he said. "It is hard to tell what effect him being missing will have as they had a good win at West Brom two weeks ago.
"If your manager is out it can leave a hole but I maintain this game is about the players. Chris Hughton (assistant manager) and Colin Calderwood (first team coach) are good people and, who knows, it might just ease a bit of the tension up there.
"Sometimes it can work in your favour and it might just be what Newcastle need right now."
