Certainly, Alexander-Arnold’s performance at Elland Road lends weight to the theory that his future lies infield.
The 24-year-old was outstanding, creating Liverpool’s first goal for Cody Gakpo and their sixth for Darwin Nunez. A driven low cross and a beautifully-judged clip over the top - classic Trent.
Beyond the assists, though, there was so much more for fans, and Klopp, to savour.
Alexander-Arnold started, nominally at least, at right-back, but spent the bulk of the game dictating play from a right-sided central midfield role. And boy did he do it well.
He had more touches of the ball (153) than any other player on the pitch. More touches, in fact, than he has ever had in a professional game. He completed 124 passes - only Virgil van Dijk managed more - with a completion rate of just over 91 percent. Thirty-four of those passes were played into the final third, at least 10 more than anyone else in red, and more than twice as many as anyone in a Leeds shirt.
There was defensive work, too. Three tackles, two of them won, an interception and a pair of clearances, with possession won back for his side more times (11) than anyone else on the field. Klopp said his favourite moment of the game came in the 92nd minute, when four Liverpool players hunted down Georginio Rutter. Alexander-Arnold was the one leading that counterpress in the Leeds half.
His touchmap was telling, with only 17 touches coming in his own defensive third, and only 12 coming in the final third. Less than a third came in what you would call a ‘typical’ right-back position, with the bulk coming in midfield.
He attempted only one cross in the entire 90 minutes, although he did clip a lovely free-kick to the back post in the second half, with Van Dijk just offside as he set up Mohamed Salah for a disallowed goal.
All in all, it was some display, the kind which will inevitably lead to questions for Klopp about where best to deploy one of his star men in the future.
