Trent Alexander-Arnold is rightfully regarded as a one-off on Merseyside. The Scouse defender has effectively refined what it means to be a full-back since his emergence at Liverpool, by proving to be different than virtually all of his peers.
As a graduate of the club's academy who is still just 23 years old, the Reds look set to benefit from his unique skill set for the next decade. As an attack-minded right-back who is his team's chief playmaker, Alexander-Arnold is as close as it gets to irreplaceable.
However, his presence in the squad is almost problematic. Alexander-Arnold is so special and still so young that it is almost impossible to find a capable deputy for him who is willing to remain on the bench for around 75% of the campaign.
