When it comes to going forward, Alexander-Arnold is crucial to everything that Liverpool do.
His 18 goals and 64 assists tell only half the tale of how vital he has been to their success in recent years.
But while Alexander-Arnold relies on his remarkable range of passing to create chances, Frimpong is a far more direct player, instead opting to dribble past his opponent.
A product of Manchester City's academy, the 24-year-old is regarded as more of a wing-back or right-winger who can drive at a defence rather than a full-back.
