It's heading towards five years since Philippe Coutinho swapped Anfield for the Nou Camp.
In January of 2018, Barcelona made Liverpool an offer that they couldn't refuse for the Brazilian playmaker as they parted company with a whopping £142m to secure his services.
That deal has long been viewed as transformative for Liverpool and destructive for Barcelona, with the Reds re-investing a considerable chunk of their windfall back into the squad with the additions of players such as Virgil van Dijk and Alisson Becker, two players who have been core to Liverpool's successes over the past four years.
