The teenager received some criticism after being exposed by Manchester United’s Marcus Rashford and Crystal Palace’s Wilfried Zaha, and although he has bounced back, he admits it has not all been plain sailing.
“There has been a lot of ups and downs and twists and turns which maybe a lot of people have not seen in training and off the pitch,” Alexander-Arnold said.
“There hasn’t always been just a steady rise, there have been mistakes and bad games along the way that help you learn.
“It is thanks to those games and the trust of the manager that helps you get through those tough moments and to come through them and learn from them and not let them get you down.
“Looking back 12 months ago I would never have thought I’d be in this situation and I am grateful for it.
“Every time he (Klopp) has trusted me to play, especially in the big games, I try to show why he has trusted me and I try to do him and the team proud.”
