The Gunners splashed around £75million on both players from Manchester City this summer.
Mikel Arteta is now expected to hand the Brazilian forward and the Ukrainian full-back their Arsenal debuts away at Selhurst Park.
"Those players have been inspired by top players, top professionals, ruthless winners for many years," said Arteta.
"They were looking at them, and now it's their turn to do the same and inspire those younger players that we have in our squad to do the same and to show them what it takes to win, and the level of detail, hunger and dedication that you need to keep winning."
Jesus has already scored seven goals during pre-season and Arteta has backed the Brazil international to maintain that form in competitive football.
"The role that Gabi has here is going to be very different to the role that Gabi had in his previous club," Arteta added.
"That needs some adaptation and time and we are all surprised with how quickly he's done it, but we have to share that responsibility.
"He's a tremendous talent with a mentality that is so contagious and he's going to give us a lot, but it's a team at the end of the day."
