New Juventus coach Gigi del Neri expects more signings to soon arrive.
Simone Pepe, Jorge Martinez, Leonardo Bonucci and Marco Motta have already been snapped up by the new Juve board.
Del Neri said: "I will treat everybody equally, although in football one player can leave and another can arrive.
"The attack is already complete with Trezeguet. Amauri, Iaquinta, Del Piero, as well as Diego. In midfield we are hard. In terms of numbers and quality I think we can stay calm when it comes to the midfield and attack.
"Marotta is still working on the defence and the wings.
"Diego can either play behind a lone striker or in midfield, but he can't play behind two-strikers.
"I have no interest in how my predecessors worked. My relationship with everyone will be based on mutual respect. Everyone has a job to do.
"Del Piero is a Juventus player and I'm counting on him as a player. He won't be a non-playing captain."
