Now the completely undisputed first-choice right-back at Liverpool, Trent Alexander-Arnold will look to build on an outstanding debut season as a senior regular at Anfield.
Still just 19 years of age, the English defender almost seems like a veteran presence despite only becoming a regular starter after the turn of the year.
But that was before Liverpool’s incredible Champions League knockout run.
It was before he was afforded the chance to go the World Cup with England and make his senior competitive debut.
Alexander-Arnold seems so assured now, so comfortable with the expectations and responsibilities that come with playing for Liverpool.
It is embodied in his tenacity. His willingness to press, harry, sprint back to cover in defensive transition, and charge up the other end with the same vigour is contagious amongst his team-mates.
He is so perfect for Klopp.
The 19-year-old still has some defensive flaws to iron out when isolated into one-on-one situations.
His slight frame is a worry, but until he can fill out a little bit more he will continue to rely on his speed and flexibility to win the ball in more creative ways than bullying attackers off the ball.
In possession, Alexander-Arnold is extremely threatening.
A former midfielder by trade, he has a devilishly good eye for a pass and managed to pull off some insane cross-field lofted passes last season.
Klopp and Alexander-Arnold were both excited to be reunited at Liverpool’s training camp in France last week.
“We want to be together, we enjoyed last season together and want to have a better one this time, so the earlier we can be together the better it is,” Klopp told Liverpool’s club website.
Bursting with confidence and anxiously waiting for the season to begin, expect the 19-year-old to again prove himself worthy of being Liverpool’s right-back for the future and the present.
