#4 Left-back
James Milner's successful reinvention was a nice story to read for 2016-17 season, but now Liverpool need a viable alternative for the upcoming season with added European commitments. The writing was on the wall for Alberto Moreno's Liverpool career the day he put in a hapless performance against Arsenal at Emirates.
Reports suggest that Klopp is on the lookout for a young player to complement and eventually take over from Milner, rather than an established star who would instantly crack the first 11.
Either way, it is increasingly clear that Liverpool need to add numbers at left-back. Links with primary target Ryan Sessegnon of Fulham have broken down in recent weeks as Klopp’s search for a left back drags on.
