He hasn't had any time with his team yet, but Bento's gone ahead and cut his team to 23 men anyway.
Portugal starts camp this week and won't play a friendly until May 31, when they take on Greece.
Why Bento even bothered to name a 30-man squad if he planned to cut it down to 23 before a single day of training camp and well before any matches were played is anyone's guess.
Goalkeeper Anthony Lopes, defenders Antunes and Rolando, midfielders Andre Gomes and Joao Mario and forwards Ivan Cavaleiro and Ricardo Quaresma were the players cut from the initial squad.
Here's the 23-man squad that Portugal will be taking to Brazil.
Goalkeepers: Beto (Sevilha), Eduardo (SC Braga), Rui Patrício (Sporting)
Forwards: Cristiano Ronaldo (Real Madrid), Éder (SC Braga), Hélder Postiga (Lazio),Hugo Almeida (Besiktas), Nani (Manchester United), Varela (FC Porto), Vieirinha (Wolfsburg)
