Hereford of npower League Two today sacked manager Simon Davey following their poor start to the season, having only appointed him in July after a change of ownership at Edgar Street.

Leicester chief Milan Mandaric, meanwhile, replaced Paulo Sousa after less than three months in charge of the Foxes and installed former England boss Sven-Goran Eriksson, making it seven managers to have come and gone at the Walkers Stadium during his tenure.

Bevan believes the policy of such rapid hiring and firing does nothing whatsoever for the overall stability of the game.

"We lost another manager this morning and it is a fairly mad world," said Bevan, who was speaking at the inaugural Professional Players' Federation national conference in London.

"I think a lot of the clubs need to take a step backwards and just think a bit more carefully because what happens when you remove the manager - whom [Arsenal manager] Arsene Wenger said is the most important man at the club, otherwise why is he the first person you sack when things go wrong? - is that if you do not deliver continuity and give the manager time, what you do is destabilise the club.

"Worse than that is you just fuel the insanity of the sport that we have in football.

"That sends the wrong messages out to the people we should have investing in our clubs.

"The other issue is it takes so many guys out of work, and it takes then 16-17 months to get back into work."

Bevan believes when the Football Association replace Fabio Capello as England manager at the end of the Italian's contract after Euro 2012, there is no reason why home-grown candidates should not be in contention.

The completion of the long-awaited National Football Centre at Burton can, according to Bevan, only aid the development of English players and coaches alike.

"We have about 62 English managers in the 92 clubs and a lot of those are up-and-coming young managers. The trick for the FA is to make sure when it is time for Fabio Capello to step down as manager that they have a choice of a dozen or more managers who fit the bill, what you need to do is ensure you invest in them," Bevan said.

"At the moment, football invests zero in technical development of its coaches, that is in leadership, man management, commercialisation and understanding budgets - if you want to survive in League Two as a manager, then you probably need to understand what budget you have got and how the club operates commercially.

"The National Football Centre will deliver results for the young players and coaches coming through.

"At the moment we have 2,769 UEFA coaches in this country - Germany have 34,000, Italy 29,000, Spain 32,000.

"It is also about quality."

Bevan concluded: "Coaches, managers, players will be going to the National Football Centre and getting good experiences.

"You hear a lot of the older guys talking about sitting down with Ron Greenwood at Lilleshall, with Bill Shankly in those days, and it is a focus point.

"It is not an Open University we want, it is a university focus point and that is what the National Football Centre will deliver."
