Sunderland boss Sam Allardyce has told young managers there's one way to keep your job: win games.

He was responding to a question about Everton's Roberto Martinez, who he faces at Goodison Park on Sunday afternoon.

"Young managers have become very protective of their own image," said Allardyce, who, at 61, is 19 years older than his opposite number.

"It is very important for them that they are seen to be doing things in the right way. That means they want to be talked about for playing football the right way.

"So I would probably have a different opinion to most young managers – and that is that football is about winning, always has been and always will be.

"The only way you keep your job is by winning. Playing football the right way and losing makes you lose your job."
