Blackpool was where Allardyce cut his managerial teeth where he was shown the door after narrowly missing out on promotion to Division One in 1996.
But the 57-year-old says he bears no grudges.
Sam Allardyce: "It's long gone, water under the bridge.
"At the time it was devastating because I thought I might have been lost to football, I thought I might not get back into the game.
"Luckily that wasn't the case but the experience I gained as a manager has stood me in good stead to go on and do better things, so I have no axe to grind with Blackpool.
"We all know how important it is from both sides - the football side and the financial side."
