Trent Alexander-Arnold continued his impressive form with a 20th appearance of the season – and fourth in a row – against West Ham United on Saturday.
Nathaniel Clyne and Joe Gomez then each played 90 minutes for the U23s the following evening, meaning the position is perhaps now Klopp’s most well-stocked.
“It’s an unbelievably important position,” said the manager, who has both Alberto Moreno and Andy Robertson in top shape on the other flank.
“It is one of the most important in world football because they were defenders but now they are sometimes defenders and sometimes attackers.
“Clyne is the most experienced one but was injured. He has speed, is technically good, he is not really an offensive player, but he protects well and helps a lot in defensive moments.
“Gomez is coming from the centre more, he will in the future play there. He has to improve but is more the defensive part for a full-back.
“Then there is Trent, who is very offensive-orientated, fantastic crosses, a good footballer.”
