10) Lazar Markovic – €25m
The then 20-year old Markovic was one of Liverpool’s most expensive purchases during the 2014 summer spending spree. The Serbian winger was bought from Benfica for a substantial sum but he was meant to fill a glaring gap in the Liverpool side – that of a genuine wide player.
Rated as one of the most promising young talents in European football and nominated for the ‘European Golden Boy’ award for 2013/14, Lazar had already made his mark by winning four league titles – three at Serbian outfit Partizan Belgrade and one at Portuguese side Benfica. He was a regular starter at both clubs, a scorer of vital goals and helped Benfica secure the domestic championship title while also being instrumental in enabling them to finish runners-up in the Europa league.
Markovic failed to replicate his European form in England, scoring just 2 goals in 19 Premier League appearances for the Reds during his first season. However, his performances during the second half of the season were encouraging and he was sent out on a season-long loan in 2015 to Turkish side Fenerbahçe. His stint with the Süper Lig franchise was hampered by multiple injuries, prompting a return to Liverpool at the end of the season.
