Hatters boss Nathan Jones spoke to the press after beating the drop with a fantastic 3-2 victory against Blackburn Rovers at Kenilworth Road.
The five-goal rollercoaster meant Town finished in 20th position against all the odds, having been six points adrift of safety when the Championship season restarted in June.
Jones said the achievement was: "Unbelievable! It’s a shame there is no fans here because I think it would be bouncing right now. The volume levels would be through the roof but so proud of the group, to get 16 points from a possible 27, nine games, is a phenomenal return considering where we were.
"I would have thought a handful of individuals would have thought we would do it, and this is as great an achievement as promotion really. It’s over a shorter period of time as I mentioned in my press yesterday, but what a wonderful achievement, I’m so proud.”
