The Championship has been the tightest and arguably the most exciting league in Europe this season, with the rollercoaster ride continuing right down to the last day. In a way, it's a pity that Birmingham and Sunderland have gone up already, out of keeping with the twists and turns of the previous months.
As it is the attention will focus on Saints and the six clubs all fighting it out for the final three play-off spots. Saints fans will of course remember a similar scenario on the final day of the relegation season as Norwich, West Brom, Crystal Palace and Saints fought it out for 17th place and safety.
At one point in that incredible afternoon each of the four teams were in pole position as results stood with West Brom emerging from the pack.
We now face a day of equal drama but in a much more positive scenario, with the chance to get into the play-offs and extend a rollercoaster season of highs and lows. As every Saints fan must know by now, to be sure of going into the play-offs we need to win and match Stoke's result.
However, Saints can still go up if we draw or even lose, although it is highly unlikely that enough of our rivals would slip up and be quite that generous.
One thing is certain, St Mary's will be absolutely jumping with the first sell-out since relegation. The atmosphere has been good this season, helped by investment in the team and unity behind the scenes.
The chance of a takeover by one of the world's richest men doesn't hurt either and if Paul Allen's reported interest does indeed materialise it could be the perfect end to a memorable season.
It's important to recognise that despite the frustrations of watching an entertaining and talented Saints team stuttering their way through this season, we have come a long way.
Lowe and Redknapp are long gone. We're fighting for promotion, not against relegation. We've kept a manager for an entire season, even if we're now getting through Chairmen at a rate of knots!
Whatever the result, Sunday will be a memorable day, worthy of so many of the last day dramas of our recent history. Let's hope we can show how far we've come since the pain of 2005 and fight our way through the play-offs to one of the greatest escapes of all - back into the Premiership.
