Darwin Nunez will complete his medical on Tuesday as he prepares to become Liverpool's first major signing of the summer.
The Reds have already agreed a deal with Benfica for the 22-year-old striker, paying a set fee of £64.1million (€75m) with a possible £12.8m (€15m) in appearance-related add-ons and further £8.5m (€10m) depending on team success.
The player was in England on Monday to undergo the first part of his medical, with the main chunk of the procedure taking place on Tuesday.
