During a dramatic news conference at the Italian Olympic Committee, the 42-year-old Roma great said during his two years in a technical role he was repeatedly excluded from strategic decisions and felt obliged to walk out of his only club.
"It was not my fault... Today is like dying. It would have been better to die", Totti told reporters. He said he would be ready to return to the club if President James Pallotta left.
Widely recognised as one of the greatest ever Italian footballers, Totti won the 2006 World Cup with Italy and spent all his club career in the yellow and red Roma strip, scoring a club record 307 goals in 786 games.

He retired as a player in 2017 and was given a job on the Roma technical staff but without a clearly defined role.
The born-and-bred Roman, Totti joined the club's youth set-up in 1989, becoming captain of the first team in 1998 and leading them to their last Serie A title in 2001, one of only three they have ever won.
The relationship between "Il Capitano" and the U.S. management led by Pallotta has often been tense, especially in the run-up to his final match as a player in an Olympic stadium full of crying fans.
"They forced me to quit football as a player. They have made many promises, never fulfilled," he said, adding he could no longer work with Franco Baldini, a club consultant formerly at Tottenham Hotspur and Real Madrid.
Pallotta's group of American investors acquired AS Roma in 2011, after almost 20 years during which the club was headed by the Sensi family of local businessmen who were close to Totti.
In May, Roma did not renew the contract of club captain Daniele De Rossi, Totti's life-long friend, fuelling the fans' bitterness towards Pallotta, who they accused of getting rid of club legends.
"Some people have always wanted Romans out of Roma. Now they achieved what they wanted", Totti said. "De Rossi and I will go to the stadium next year, into the stands with the fans".
