The right-back struggled for large spells of last season on the pitch as Klopp was left severely shorthanded in the defensive department owing to injuries to key players in the likes of Virgil van Dijk and Joe Gomez.
However, Alexander-Arnold has been among the standout performers for the Reds this season, registering nine assists in 13 games across all competitions.
Liverpool legend Barnes stressed that when a squad are missing players, it can affect the performances of the rest of the team and believes the 23-year-old is back to his best this season after key centre-backs returned from injury.
“Trent Alexander-Arnold is back to his best thanks to the players he’s playing with”, Barnes told Bonus Code Bets.
“When you are missing certain players, that affects the whole team.
“Last season they had two key central defenders missing.
“But now that they have those two central defenders back, the full backs can do what they normally do.”
However, Barnes insists that Klopp has not done anything to help Alexander-Arnold get back to his top form and rather the return of key players from injury means that the team are more suited to accommodating him, which has allowed him to flourish again.
“If they lose those centre backs again, Trent won’t necessarily continue what he’s been doing over the course of the first 14 games of the season, because it affects the way the team plays.
“That is how comprehensive Liverpool is. Having the first team out there positively effects everybody.
“Klopp hasn’t done anything but it’s just that the team is now suited to him, whereas last year, because of the injuries, it probably didn’t.”
Liverpool are set to return to Premier League action at the weekend when they host Southampton at Anfield and fans will be hoping Alexander-Arnold will keep on pushing after a strong start to his campaign.
