Alexander-Arnold has impressed since his introduction into the senior setup, with 34 appearances being made in all competitions, but both of Manchester United's goals in the 2-1 win over Liverpool last weekend came from the right-back's side of the pitch.
However, Klopp has backed Alexander-Arnold to continue to improve this season, saying that the 19-year-old is deserving of his place in the starting lineup.
At a press conference, the 50-year-old told reporters: "The reason Trent is playing is not because he's Trent or he's a Scouser. It's because of his quality.
"His strength is a little bit more in the offensive side. The goal was bad defending but not him alone. Because of his age he will make mistakes, but will learn."
