The Bianconeri allowed reserve goalkeeper Marco Storari to join Cagliari on Thursday but wasted little time in acquiring a new understudy for current No.1 Gianluigi Buffon.
"Norberto Murara Neto has officially completed his move to Juventus, penning a four-year contract that keeps him with the club until June 30, 2019," read a statement released on the Italian champions' official website on Friday.
"The Brazilian goalkeeper, 25, joins following four-and-a-half seasons with Fiorentina where he displayed the credentials which have led the Bianconeri to recruit him as Gigi Buffon’s deputy."
Neto joined Fiorentina from Atletico Paranaense in 2011 and established himself as the Viola's No.1 during the 2013-14 season.
The Selecao shot-stopper was dropped to the bench last season after deciding against signing a new contract with the club, but was restored to the starting line-up following an injury to Ciprian Tatarusanu.
