Coventry City manager Chris Coleman has admitted to a huge sense of relief after seeing his side beat the drop despite being thrashed 4-1 at Charlton Athletic.
The Sky Blues escaped by a single point and Coleman wants to avoid further struggles next season.
He told the Evening Telegraph: "That was the worst game in terms of stress in my management career, by far.
"Although we have stayed up it was agonising and I never want to experience that again. I have experienced it as a player, but as a manager it is different.
"We have been in a relegation dogfight for the last few months and now it is finally over, but that's not the way to do it, that's not the way to secure your place in the Championship.
"We said all along we must not end the season depending on anyone else and go out with a whimper, but that's what we have done.
"We have stayed up by the skin of our teeth, by one point, so now we have to look at what we have to do. We have to look how we change it and say this is where we have to improve.
"We know where we have to strengthen in a lot of places and if we don't do that we will struggle again next season."
