Chelsea goalkeeper Petr Cech admits the stability at Manchester United is his preferred managerial model. Cech has already played for eight different managers during his nine years at Chelsea and admits the constant uncertainty has not always helped.
But he also believes every change has provoked an immediate improvement.
Cech said: "The easiest way to cure the problem is with the electric shock of a change of manager.
"You can't change 20 players in the middle of the season so it always becomes dangerous for the manager if you have a spell where nothing is working.
"Unfortunately we've experienced that a few times and the result was always that the manager left.
"And every time you can see the instant reaction of the team, how quickly we get over the situation and improve things.
"It's a difficult one because you really don't want to be changing your manager every year but at the same time you can see that this policy has worked for Chelsea.
"If you see the stability and organisation Arsenal have, it's amazing. But ask their fans about the last eight seasons and they'd say they don't like it as they haven't won anything.
"We can say we'd like more stability at Chelsea, but we always seem to get a trophy at the end of the season and I think our fans would rather have that.
"The ideal situation is the Manchester United scenario where you have the same manager and still win a large number of trophies. But we seem to prove all these theories wrong."
