#3 Naby Keita (€60 million)
Naby Keita was such a revelation for many when he played for RB Leipzig. A sharp, agile player who co give pinpoint passes to his teammates, the Guinean was touted by many to become one of the best midfielders in Europe. With that complete skill-set, no wonder that Liverpool finally bought him as their most valuable midfielder.
The 24-year-old did impress for his team at the beginning of the season. Despite his bright start, Keita is now enduring a mixed season for the Reds. He often goes in and out from the starting 11 and has been deployed in several positions by Jurgen Klopp.
He became an unused substitute in Liverpool's most recent match against United, while regularly starts in several previous games. Overall, he is yet to live up to his huge price-tag because of this inconsistency and an abysmal goal/assists contributions for his team.
