The visitors, meanwhile, will be looking to return to winning ways in Friday's friendly after failing to win their last two matches.
Match preview
Three years after leaving his position as Hertha BSC boss, Jurgen Klinsmann returned to football management earlier this year when he was announced as Paulo Bento's successor.
Bento left his position following South Korea's last-16 exit at the 2022 World Cup, ending his four-year stint as manager of the Taeguk Warriors.
Klinsmann began his tenure during the March international window, overseeing a 2-2 draw against Colombia in his first game in charge.
Just days later, South Korea went on to lose 2-1 to Uruguay in Seoul, leaving Klinsmann without a win in his opening two matches.
The 58-year-old will be desperate to get his first win in the next two friendlies against Peru and El Salvador, otherwise, his wait for a victory will continue until September.
In contrast to their hosts, Peru failed to qualify for the World Cup in Qatar, but they ended 2022 on a positive note, recording three consecutive victories.
Unfortunately for La Blanquirroja, they were unable to carry that impressive form into the March international window, where they failed to win either of their two friendlies.
After losing 2-0 to Germany in Mainz, Juan Reynoso's side played out a goalless draw with 2022 World Cup semi-finalists Morocco.
With a year to go until the start of the Copa America, Peru will be looking to build momentum, starting with their upcoming friendlies against South Korea and Japan.
Having scored failed to score more than one goal in seven of their last eight matches, the South Americans will be hoping to show an improvement in front of goal on Friday.
