Darwin Nunez is set to cost Liverpool millions if he makes his tenth appearance for the club against Manchester City next weekend - as he is expected to do so.
Liverpool splashed out £64.2million (€75m) up front for the Uruguay international striker in the summer window, but the transfer included a number of add-ons that are set to be triggered over the next few years.
And the first of these could be triggered as early as next week when Liverpool play host to Pep Guardiola's champions Man City, after a mid-week trip to Glasgow to take on Rangers in the Champions League.
