The Reds will be looking to build and improve on their 1-1 draws with Wacker Innsbruck and Stuttgart in midweek as they take on Klopp’s former side Mainz this evening.
A trip to Grodig and the 3,500-capacity Greisbergers Betten-Arena should see Liverpool take to the field with a stronger side than before, looking to seal victory over their Bundesliga opponents.
Klopp plans to make changes throughout the ties, and could be boosted by the return of a number of players, though doubts remain over at least two.
Here’s how Liverpool could line up in either half of their clash with Mainz.
Kelleher is now back fit and is set to be involved against Mainz, with it likely that Loris Karius drops out having been drafted in against Wacker Innsbruck and failing to impress.
Nat Phillips, Curtis Jones, Marcelo Pitaluga, Ben Woodburn and Mateusz Musialowski all sat out the opening two friendlies but it is assumed they are able to be involved on Friday, along with Neco Williams and Harry Wilson.
Defenders: Konate, Matip, Alexander-Arnold, Tsimikas, B.Davies, R.Williams, Phillips, Koumetio, N.Williams, Beck, Bradley
Midfielders: Milner, Keita, Oxlade-Chamberlain, Jones, Woodburn, Cain, Clarkson, Morton
Forwards: Salah, Mane, Minamino, Origi, Elliott, Wilson, Gordon, Musialowski
Liverpool XIs vs. Mainz
Klopp has already confirmed he plans to use two different XIs for the game, with 11 changes set at half-time, and it would make sense to name a stronger side to start.
Kelleher; N.Williams, Matip, Konate, Tsimikas; Milner, Keita, Elliott; Salah, Mane, Oxlade-Chamberlain
With Alexander-Arnold poised to captain the side again, the returning Phillips could line up alongside Rhys Williams at centre-back, with young Owen Beck the next viable candidate at left-back.
Musialowski would be an eye-catching addition, however, and could feasibly start over Gordon.
Adrian; Alexander-Arnold, Phillips, R.Williams, Beck; Clarkson, Cain, Jones; Gordon, Minamino, Origi
With those two sides available, Liverpool can expect a strong display against Klopp’s former club, while the manager will have a number of interesting options on the bench.
There can be few conclusions drawn from an early pre-season friendly, but Liverpool are getting closer to full strength in terms of personnel and can hope for a comprehensive win in Grodig.
