One of those few changes was enforced last time out, as centre-back Christian Ramos was suspended with Miguel Araujo stepping up in his absence, and Ramos is expected to slot back into the starting XI on Friday.
He should join Alexander Callens at the heart of the back four, with Aldo Corzo and Miguel Trauco featuring in the full-back positions.
The back four will receive plenty of cover from the experienced pair of Yoshimar Yotun and Renato Tapia, as they will sit deep and break up any Paraguayan attacks before they develop into real threats.
That allows more freedom for the front four to attack, with the line being led by Gianluca Lapadula since Ricardo Gareca's decision to leave record goalscorer Paolo Guerrero at home.
Lapadula is supported by the exciting trio of Christian Cueva, Sergio Pena and Andre Carrillo, who has netted two goals in his four Copa America appearances this year.
THe quality in that three behind the forward will undoubtedly cause problems for the Paraguay defence with their pace on the counter and impressive link-up play.
Peru possible starting lineup: Gallese; Corzo, Ramos, Callens, Trauco; Tapia, Yotun; Carrillo, Pena, Cueva; Lapadula
