Steve McClaren admitted he could have no complaints after being sacked as England coach.
McClaren was dismissed in the aftermath of Wednesday's decisive 3-2 defeat against Croatia that confirmed England would not qualify for Euro 2008.
English Football Association chief executive Brian Barwick phoned McClaren to confirm the decision on Thursday morning.
Just hours later, McClaren made a dignified appearance to discuss his exit and conceded he had to shoulder the blame for the end of his brief, ignominious reign.
"This is one of the saddest days of my career. 18 months ago when I got the job was one of the proudest days of my career and I was honoured to be the England coach," he said.
"I enjoyed every minute. It's just sad to be relieved of my post but I can understand the decision by the FA.
"I'm not making any excuses. We had enough games to do it. I can talk about conditions, injuries, bad luck, decisions, but ultimately it's 12 games and we failed to qualify."
"I've got huge disappointment for the people who are really losing out. That's the country and the fans. So it's a regret that we didn't qualify."
McClaren is convinced he is a better manager despite his torrid time with England and is determined to get back into the game as soon as possible.
"I believe I'm a better manager than I was 18 months ago," he said. "What I've been through has made me better. It's failure but I'll learn from that and move on.
"All I can concentrate on is getting over this huge disappointment and looking forward. I'll recover, I'll bounce back and wait for the next challenge. I'm not one to lie on the beach."
