AFC Wimbledon manager Neal Ardley claimed he always believed his side would avoid relegation after Jack Midson's penalty saw them seal League Two survival with a 2-1 victory over Fleetwood.
Jack Midson struck from the penalty spot with 18 minutes remaining after Andy Mangan had cancelled out Gary Alexander's header in a dramatic second half.
Victory lifted the Dons out of the relegation places and instead condemned Barnet, with whom Midson spent a spell on loan in 2011, to non-league football next season.
And Ardley, who took over as manager in October, insisted his side had got their reward for keeping the faith.
He said: "We said to the players 'it's in the script, we are staying up'.
"I said if we concede a goal and fall behind then I want every single player to think this is part of script and we will come back, and it seemed to work because every time we've gone behind we came back."
Fleetwood manager Graham Alexander said: "We have way too many players at the moment. We'll be looking to carry about 10 less so there will definitely be players leaving.
"We have to make sure we can bring in players with the right character and mentality for this division because I think we have the ability but we're lacking in the mental and physical side.
"We have identified some players and we know where we need to act. I won't be having a break, while we have this period of no games I need to do everything to make sure we are competitive for next season."
