Brighton lost the first leg 2-0 on Friday evening when they played the final half-an-hour with ten men after four players went off injured.
In a message to supporters on the club website, Bloom said: “Over the last nine months, our players have been outstanding - and they deserve to achieve something on the back of their superb efforts this season. They have made this one of the most memorable seasons in the club’s 115-year history.
“In almost any other year our points tally would have proved enough for automatic promotion, but on Monday night that counts for nothing.
“Our players were magnificent on Friday night in the most difficult of circumstances. We hardly conceded a chance while playing the last 30 minutes with ten men, having had four key players injured during the game. This has given us a real possibility to progress, and one the players are determined to take.
“We’ve faced bigger battles, longer odds and tougher tasks in our time, yet still come through to triumph against the odds. We are Brighton, we know the deal: more often than not we have to do things the hard way.
“Throughout our history we’ve taken knocks, setbacks and injustice in our stride and come back stronger, time and time again. Let’s do that now, players and fans together.
“This group of players have a belief that they can still achieve our ultimate goal. They know it won’t be easy, and they know success never comes easy. It will take huge amounts of spirit and passion from the players and the fans for us to win through on Monday night.
“Our fans were once again outstanding on Friday, and I implore every single fan to get right behind the players throughout the game. We need you to pack the Amex, turn it blue and white and create a fantastic atmosphere.
“Sing, be loud, make the Amex a bigger cauldron of noise than it has ever been. Don’t let up from the first minute to the last - this will be the inspiration that will help the players get the result that we all deserve to help us to Wembley.”
