Cardiff City boss Malky Mackay has slammed the attitude of club owners over the spate of sackings in recent days.
Mackay is particularly bemused by the failure to notice the success the likes of Sir Alex Ferguson, Arsene Wenger and David Moyes have enjoyed when trusted with long tenures in charge.
"The short-termism has got worse," said Mackay, who has been in charge of Cardiff for two and a half years.
"I remember talking to Sven-Goran Eriksson when he was Leicester manager. We were talking about his career and he had five-year tranches at three different football clubs in Italy and Portugal.
"That very rarely happens nowadays. Certainly in the last five or 10 years it has become less and less.
"If you are looking at somebody in a job in the Premier League for two or three years, they are one of the longest serving managers, which is crazy but it's the way it is.
"If you look at the likes of the top sides, Manchester United, Arsenal and Everton had managers in charge for a long period, 27 years, 17 years and 11 years for the three managers.
"Look at the stability and the strength of those clubs over that period, having good people at the top who have got the vision going forward on how the club should be.
"There is no coincidence that there is stability at those clubs."
