Ian Holloway insists Leicester will be back in the Championship quickly - but he is not sure he will remain manager.
The Foxes slipped into the third tier for the first time in their history after they failed to beat Stoke and Southampton saw off Sheffield United.
Asked if he feared owner Milan Mandaric would axe him he said: "Of course I do.
"Milan's going to be as devastated as anybody - we did the worst thing and got relegated. Nearly everything we've touched here hasn't worked."
Holloway became Leicester's fourth permanent boss in a year when he took charge after leaving Plymouth last November.
The club were 17th at the time and their struggle to score goals led to a sequence of poor results which saw them slide down the table.
Victory over Stoke would still have ensured safety, but Gareth McAuley hit the post and Potters keeper Carlo Nash made some outstanding saves.
"It's a devastating day for all of us. Too many times this season we haven't done it, we haven't scored and the table doesn't lie," Holloway admitted.
"Our character needs to be looked at, the overall team and squad. The fans have known it but we've let everyone down.
"Leicester City will be back, probably in a very different form with different people playing for them"
"We have to hold our hands up, we were the ones with the responsibility and couldn't deal with it.
"Our fans have been different class and they deserve a team that fights and battles and plays like we did at Stoke every week.
"It's a marvellous club and it's had far too many changes but I will say Leicester City will be back, probably in a very different form with different people playing for them.
"We'll have to wait and see how it pans out but the overall season has been a disaster and it's culminated in this."
