Sam Allardyce does not have any ill feeling against Blackpool, despite being sacked by the Seasiders in 1996.
The West Ham manager lost his job at the Seasiders after he missed out on promotion to Division One 16 years ago.
Blackpool stand in the way of Allardyce's West Ham side, as he tries to fulfil his promise to lead them straight back to the Premier League by winning Saturday's play-off final at Wembley.
But the former Blackburn and Bolton manager insists he bears no grudges.
He said: "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."
Instead, Allardyce is fully focused on the club's biggest game since their last play-off final victory in 2005.
The game is being touted as a £90million shoot-out and the 57-year-old is fully aware of its significance.
He continued: "It is important for the status of everyone at the club, particularly for myself and my staff and the players who require Premier League status again.
"It gives them a greater standing in the game. It gives us all a greater status in the game, a huge amount of revenue into this club and it gives us worldwide branding.
"We all know how important it is from both sides - the football side and the financial side."
