The 22-year-old signed for Liverpool for around 70 million euros over the next five seasons.
Dominic Zuboszlay's presence will add a boost to Liverpool's midfield after Alexis McAlister joined a while back.
So what can Dominic Zuboszlay and Alexis McAlister do?
Tactics, the Reds built up a Liverpool midfield that was worn out by age and injuries that often hindered it. Something like the suffocation of Thiago Alcantara and Curtis Jones, a future project.
Klopp has modernized the Reds' midfield by signing Dominic Zuboszlai, who can play as number 8.
He can complement Max Allister, Harvey Elliott, Jordan Henderson and Thiago when they return to the field.
Jurgen Klopp's 8th position is a form of defense with more ball control and ball development in building offense.
Thiago Alcantara showed it last season before his injuries subsided, but Curtis Jones has taken on the tough job.
Jones showed great determination in Jurgen Klopp's system, assisting the defense, passing the ball forward and supplying the attackers.
So what about Dominic Zuboszlay? According to Liverpool Insider, Dominic Jubosleigh will move to the right side of Liverpool's midfield.
Alexander-Arnold intervenes in the main attack and covers the right wing when Mohamed Salah moves from the penalty area.
Liverpool have Harvey Elliott, who is expected to succeed Henderson. Although he has the pace, he is in his 20s physically inexperienced for a duel.
There is one weakness compared to Dominik Szoboszlai that can compensate for this shortcoming.
It would make sense for Alexis Mac Allister to be part of a double pivot in Jurgen Klopp's system of play.
The former Brighton player isn't a great striker, but he has an advantage in terms of passing that can break opposition defences.
Then use penetrating lures to build attacks from below and when switching.
