Arsenal boss Arsene Wenger has big concerns over the growing sack culture inside the Premier League.

Wenger, whose side face Newcastle on Monday, feels regular managerial dismissals will mean a decline in standards.

"After a game there's a trial going on everywhere and the clubs need to be stronger," said Wenger.

"We have some countries, like Brazil, where they have five or six managers at a club in the same season. [If that happens] then nobody will trust a young player again because if they lose one game then he is out. Nobody will educate a player if he knows after one game he's out.

"The people who invest money will want the freedom to sack who they want but it's in their interest to have stability. If you have 20 billionaires in the Premier League, there will only ever be one champion and three clubs that go down.

"I believe you want competent people in charge and competent people demand people with quality to do the job. If instability comes too quickly you might suffer."
