Craig Short says he still feels numb after being sacked as Notts County boss after less than five months in charge.
Short was dismissed on Sunday because results were not deemed good enough with the team 16th in League One.
"I was shocked and a little bit frustrated but it's mainly numbness," Short told BBC East Midlands Today.
"We'd won four out of six at home. Things could have been better but we were getting there. We were four points off the play-offs so it's frustrating."
Short had won five and lost seven of his 13 league fixtures in charge of the Magpies.
But the former Sheffield United defender, who was only
appointed in the summer
following Steve Cotterill's decision not to sign a new deal, felt the decision to sack him was more than a little harsh.
I was enjoying it, I found it stressful at times but I enjoyed the challenge and the responsibility. It has whetted my appetite. I want to continue
"I know it's a progressive club and it wants to be looking at the top end of the division but I thought we were doing well, playing some good football and not getting a great deal of luck in our away games," he said.
"Lots of clubs have high expectations but considering this is a club that has just come up from League Two - to automatically think they would go into the Championship straight away is very ambitious.
"I know it's an ambitious board but we have Championship clubs come down in Peterborough, Plymouth and Sheffield Wednesday and they have not had it their own way.
"The start of the season was poor and I admit that - and if that had continued I would have resigned anyway - but since then performances have improved, the players have given everything and we just needed a little bit more luck.
"It's a shame but we are in a ruthless business."
Paul Ince has been tipped as the favourite to take over from Short, while former Nottingham Forest manager Paul Hart, Crawley boss Steve Evans, Mansfield Town chief David Holdsworth and Peter Reid have also been linked with the post.
And Short feels his replacement will have a fine team to work with.
"I've left a good squad and a good set of lads," the former Notts, Derby, Everton and Blackburn defender added.
