Baggio had recovered from an injury in record time, but was left out of the squad going to Japan and South Korea by Italy Coach Trapattoni.
"It would've been my fourth World Cup and I should have been there. It was right. It was sacrosanct," he told the Italian edition of Vanity Fair.
"Considering the career I'd had, I had that right. They should've taken me along and given me that chance, even if I was in a wheelchair.
"FIFA had just expanded the squads to 23 players and they did it so that Ronaldo and I could participate, as we were both coming off injuries and could've been considered a risk.
"One more man, what was the problem? Instead Ronaldo went, he was born again and he won the World Cup as top scorer. I stayed at home."
