Liverpool were pipped at the post against Napoli in the Champions League this evening. It was certainly not the best of performances from the Reds but it seemed they were going to sneak away with all three points. However, a 90th-minute goal from Lorenzo Insigne gave the Italian side a deserved win.
Several players failed to live up to their usual standard, including right-back Trent Alexander-Arnold.
He may be a supreme talent and included on the Golden Boy shortlist, but he is still only 19-years-old.
His performance was understandable given his workload recently and Liverpool boss Jurgen Klopp needs to ensure he perfects a balancing act with the player.
In Nathaniel Clyne, Liverpool have a fellow England cap in their ranks who can easily step up when it is time to give Alexander-Arnold a week off. They also have James Milner, Fabinho and Joe Gomez who are more than capable in the same position.
Asking a teenager to play 40-plus games in a season would be poor practice from Liverpool and leave Alexander-Arnold struggling to put in his best performances.
It has been tough for Klopp to do this over the past three games. Chelsea back-to-back and then Napoli left him needing to play Alexander-Arnold in two big games in quick succession.
However, Liverpool need to ensure they give Alexander-Arnold the chance to rest when needed. Otherwise, they risk leaving him burnt out for when really needed.
