Manchester City assistant manager Mikel Arteta and Nice boss Patrick Vieira were options along with Allardyce, who Sportsmail revealed rejected the opportunity after being approached about the job last week. However, he'd suffer empty promises from Ashley, which future Newcastle coaches would deal with - most notably Benitez, who has since taken charge at Chinese Super League outfit, Dalian Yifang.
The former England boss, who held the position at St James' Park from 2007 until 2008, was under consideration to replace Rafael Benitez, who left the club at the end of June.
"It never really got to the sort of talks people are suggesting". I politely said "no".
"I never got to talk to Mike, it was just my agent contacted me and I had a quick think about it and a look at the situation".
With The Owls well into their pre-season programme, this could cause major issues with their preparation for the new campaign, giving them little time to source, speak to and successfully sign up a replacement in time for them to have any impact on either the transfer market or their current squad before the first game of the season, not ideal at all.
"Allardyce continued: "'It wasn't something I thought about for too long. It was better that I made a quick decision for everybody because they're in pre-season now.
"As we all know from experience, in football, just as in everyday life, when people show you respect and affection and do everything they can to make things easier for you, life is much happier, even when you face hard moments".
Newcastle have suffered two Premier League relegations under the ownership of Ashley.
Allardyce previously managed Newcastle for 24 matches in all competitions, winning eight.
