Newcastle United boss Sam Allardyce insists his enlarged backroom team will bring success to St James' Park.

"I know what I am doing," Allardyce told the People. "I know what staff to select and how to get that staff to produce their maximum.

"There are people out there who are better at certain areas of the job than I am. I am not frightened to bring in someone who is better than me at doing something. Other managers might be, but I am not because I am not a megalomaniac.

"I believe having a good staff helps to bring success and it works for me because I am good at it.

"You start to progress by finishing a lot higher than we finished last season. It's all about getting back into the top end of the Premier League, which Kevin Keegan and Sir Bobby Robson did.

"Since then there's been a lot of decline in the club and we've got to build it back up again."
