The Reds are trialling the services of Thomas Gronnemark with their academy kids — and will roll out the experiment with the first-team too if it proves successful.
The Merseysiders are the first English team to have admitted using the Dane, who has devoted himself to his set-piece art during the past 15 years.
Gronnemark uses video analysis to school players in how to best use throw-ins to maximum effect, most obviously in the opponents' final third.
He estimates the two teams in Denmark's top-flight he has coached added an extra 20 goals to their tally between them due to improved technique.
