"I failed to train the team well enough. I did expect something form the game but it didn't happen," he added. "Who trained the players? who deployed the players? Me."
Lippi didn't admit that his comeback was a fiasco. "I came back with enthusiasm. I'm not saying that I want to replicate the success in 2006 but I really expect we could perform differently."
Lippi planned to take a few months off after the World Cup. "And we'll see," said he.
"I'll be be out there to take on criticism, and actually you start to take on criticism before the match," he added. "Good luck to my successor and thanks to everyone for the last four years."
Lippi will be succeeded by Cesare Prandelli, who used to be head coach of Fiorentina.
