Wirtz, a £125m signing from Bayer Leverkusen, has had a quiet start to his Anfield career, while former Bournemouth fullback Kerkez was hooked before halftime in last week's win at Burnley.
But on Wirtz, Saunders told Tribalfootball.com: "I’m not worried about Wirtz at all. He’s been a part of four winning performances, so what more can you really ask for?
"I would have maybe liked to have seen a few more flashes of genius, as I know he has that in him. It’s hard to play as a number 10 against a low block, but he needs to get used to it, as teams will set up like that against Liverpool all season.
“He operates in those spaces between the midfield and defence, and when teams attack Liverpool, these gaps will grow and he will find success.
"Once he forms a better relationship with (Mohamed) Salah, I’m sure both players will impact games a lot more. However, the best players find ways to impact every game, and he is a great player, so I will be expecting more from him as the season progresses.”
Bouncing back
Meanwhile, Saunders is also confident Hungary fullback Kerkez will adjust to the demands of being a Liverpool in swift time.
He also stated: “Milos Kerkez has big boots to fill, and it hasn’t been the easiest start to his career at Liverpool. Personally, I still think Andy Robertson is one of the best left-backs in the world. Liverpool only lost a couple of games last season, so he can’t have done that much wrong.
“But I’m sure Kerkez will bounce back. He will have to adjust to the line Virgil van Dijk and Ibrahima Konaté set, which will be strange for him. However, if the long-term plan is for Liverpool to transition from Robertson to Kerkez, then there is no better left back in the world to learn from than Andy Robertson.”
