Last season, Blackpool were able to stun the world with an impressive sixth place finish in the Championship, after being predicted to get relegated to League One at the start of the season by many experts.
In the Championship playoffs, Blackpool were able to defeat Nottingham Forest and Cardiff City to reach the Premier League for the first time in their history and the first division for the first time since 1973.
After reaching the Premier League, not much was expected of Blackpool and many expected them to finish in last place.
But after a stunning 4-0 win at Wigan to start the season, Blackpool have been one of the best and most intriguing stories of this season.
Throughout the first half of the season, Blackpool continued to find ways to stun the Premier League establishment starting off with their energetic manager Ian Holloway.
With an outspoken style, Holloway spoke out against the establishment throughout the season and threatened to quit several times over actions such as punishment from the FA for putting out a weakened side against Aston Villa in a 3-2 loss.
However, losses such as the one to Villa did not overshadow some fantastic performances, such as completing the league double over Liverpool for the first time since 1946-47 and wins over Stoke City, Sunderland (who still had Darren Bent), Tottenham and Bolton.
However, a bad stretch between the middle of January and the middle of April that saw Blackpool pick up just six points in a 13 game stretch appeared to be the demise of Blackpool.
But this was before the last four match matches that Blackpool participated in that saw the Tangerines pick up six points put to put them back into the hunt to stay up in the Premier League for another season.
On Sunday, we will see one of the greatest relegation Sunday's in history with five different sides in position to grab the two remaining spots to get sent down to the Championship.
In Blackpool's matchup, they will travel to Old Trafford to take on the Premier League champions Manchester United.
But because Man United have reached the Champions League final, they will rest many starters in their final competitive match before the final.
Obviously, nothing has been easy for Blackpool this season, but if they can register a win at Old Trafford (or even a point for that matter), Blackpool can easily extend their Premier League run for another season and continue to build from there.
