How Jurgen Klopp's German compatriots have fared at Liverpool

KARL-HEINZ RIEDLE (1997-1999, 76 matches, 15 goals, Honours: 0)

Signed as experienced support for Robbie Fowler, he was relegated to a back-up option by the emergence of Michael Owen.

DIETMAR HAMANN (1999-2006, 283 matches 11 goals, Honours: Champions League, UEFA Cup, 2x FA Cup, 2x League Cup)

Provided central defensive midfield cover for a young tyro named Steven Gerrard. Was one of the best in the business in that role.

MARKUS BABBEL (2000-2004, 73 matches, 6 goals, Honours: UEFA Cup, FA Cup, League Cup)

Played in 60 of 63 games in the treble-winning year of 2001 and his qualities were under-rated. Would have enjoyed longer success had he not been struck down by the debilitating Guillan-Barre syndrome.

CHRISTIAN ZIEGE (2000-2001, 32 matches, 2 goals, Honours: League Cup)

Controversy accompanied his signing from Middlesbrough - for which Liverpool were fined for an illegal approach - but it was a short-lived move lasting just one season.

SAMED YESIL (2012 - to date, matches 2)

Prolific at youth team level for Bayer Leverkusen, the Germany Under-21 international's career has not taken off at Liverpool due to two cruciate knee ligament injuries. Currently out on loan with Swiss side Luzern.

EMRE CAN (2014 - to date, matches 51, goals 1)

Signed as a midfielder but played mainly in defence by Brendan Rodgers, the Germany international has yet to settle in one position. Best form has been as a third centre-back.
