But as we all know, football is a cruel game. A very quick lapse of concentration defensively saw United equalise, before an Ian Evatt own goal saw the Seasiders fall 3-2 down and condemn them to life back in the Championship.
As most have been saying, Blackpool and their manager Ian Holloway have been a "breath of fresh air" in the Premier League this season, with their free-flowing and at times carefree football despite their lowly status as Premiership rookies, as well as Holloway's always colourful press conferences.
But ultimately, they were not good enough to stay in the league and now drop back into England's second tier.
So, where do the Seasiders go from here?
