Liverpool, the defending Premier League champions, are yet to publish their official financial statement for the 2019-20 season but are expected to do so in the coming days.

With Liverpool failing to go beyond the last-16 stage after their loss to Atletico Madrid, limited progress in the Champions League saw reduced broadcast revenue from the competition.Meanwhile, at Real Madrid, Paris Saint-Germain, Bayern Munich and Juventus, loss of matchday income is what largely contributed to their respective financial losses.
