Accrington Stanley boss James Beattie personally thanked all his players after their 2-1 win over Oxford United at the Kassam Stadium guaranteed safety.
Goals from Kayode Odejayi and James Gray proved enough for Stanley to get the three points they needed to ensure League 2 football for another season.
Ryan Williams pulled a goal back for Oxford in the 67th minute, but a 10th defeat in their last 14 games means it has been a catastrophic collapse for the U's after they topped the table in December.
York City's 1-0 win over Newport County secured the Minstermen a play-off place, leaving Oxford's new boss Gary Waddock to lick his wounds after his players were booed off at the final whistle
Beattie, though, was delighted.
He said: "It was a fantastic win for us. The recovery is now 100 per cent complete. All season we believed.
"We embarked on a journey as soon as I walked through the door and although we had a sticky patch at one stage, to do it in style as we did today, and to make sure we've secured (Football) League football for another season is a great achievement for the club.
"We came here knowing we wanted to quieten the home crowd and after 10 minutes you could hear a pin drop in this stand.
"When we got ahead we were stressing to the players not to rest on our laurels.
"They deserved the result.
"We only really caused our own problems, through dilly-dallying at the back or through a couple of individual errors.
"I'm just delighted for the players. This time last year I was a player in that dressing room.
"It's been a great journey for me in my fledgling football management career."
Oxford, who have scored just seven goals in their last 13 games, have plummeted like a stone since Christmas, and Waddock said he understood the unhappiness of the fans.
"I'd like to say how unacceptable that was for our supporters and for our chairman.
"Since I've been here only Plymouth away (when Oxford won 2-0) has been very good. The other games have not been acceptable.
"We have a losing culture here and we have to change that.
"That's not a Gary Waddock performance, and not a performance I want to see from any team of mine.
"I know what needs to be done, and there will be a lot of work in the summer.
"This was our final home game of the season and I expected us to play with a hunger and desire. What I saw was just not acceptable."
