The veteran forward is critical of the Azzurri's provisional list to take to the World Cup, where he sees Brazil and Uruguay as two of the favourites to be champions
Toni's 21 goals in 35 games this season had seen him linked with a return to the Azzurri setup, despite the 36-year-old having not played for the national team in five years.
Despite accepting that he was always an outsider to make the provisional list, never mind the final 23-man squad, the former Bayern Munich forward has his doubts over some of the players whom Prandelli might take to Brazil.
"Prandelli made some choices I did not expect," Toni told Verona's website.
"My absence was already expected, I was not part of the team during World Cup qualifying but I am surprised by Alberto Gilardino's exclusion."
Italy suffered a humiliating group-stage exit four years ago after winning the trophy in 2006 and Toni thinks that they must concentrate on winning rather than playing pretty football.
"Playing a beautiful style of play is not enough, you have to win," the attacker added. "To do this we must be strong in such a hard group, as we did in 2006 in Germany.
"I think that Brazil and Uruguay are the pre-tournament favourites."
