#2 Lazar Markovic (Liverpool, on loan at Anderlecht)
Serbian winger Markovic was an exciting young talent with Partizan and Benfica. His performances eventually caught the eye of Liverpool, who signed him for £20 million in 2014.
He made 19 league appearances for them in his debut season and hasn't played for them since then.
It's difficult to see him having any kind of a future at the club, with Mane, Salah and Firmino being in the form of their lives.
Having spent loan spells at Fenerbahce, Sporting CP and Hull City, he failed to make much of an impact at any of those clubs. A string of injuries has severely limited his playing opportunities.
Klopp actually chose to keep him at the club at the start of this season, but there was virtually no chance of him making the first team. He eventually joined Anderlecht on loan last month but is apparently set for a lengthy spell on the sidelines due to his low fitness.
