Liverpool's friendly clash with Hertha today will be the first match in the club's history to use video technology.

The video assistant referee (VAR) system is currently being trialled by the International Football Association Board across a number of competitions.

There are four types of calls that can be reviewed: goals, penalty decisions, red cards and cases of mistaken identity.

The on field referee can request that the video assistant referee reviews an incident on a monitor or the VAR can recommend a review to the official.

Any player who demands a video review or enters the area where the referee is conducting an on field review (OFR) will be booked.

The use of video technology proved controversial at this summer's Confederations Cup. Chile defender Gonzalo Jara appeared to elbow Germany's Timo Werner in the face during the final, but after the VAR system was used he only got a yellow card.

Jurgen Klopp has named a 22-man squad for today's game which kicks off at 5pm in the UK.

Sadio Mane, Emre Can and Andy Robertson have travelled to Berlin but eight players have remained at the Reds’ training base in Rottach-Egern, Bavaria.

Trent Alexander-Arnold, Ben Woodburn, Marko Grujic and Danny Ings stayed behind to train.

Loris Karius (hip), James Milner (thigh), Nathaniel Clyne (hamstring) and Danny Ward (knee) are ruled out due to injury.

Liverpool squad to face Hertha: Mignolet, Grabara, Moreno, Klavan, Matip, Gomez, Robertson, Lovren, Flanagan, Ejaria, Henderson, Firmino, Solanke, Sturridge, Salah, Origi, Coutinho, Mane, Kent, Wijnaldum, Can, Lallana.
