3) Karl-Heinz Riedle (1997-1999; 76 games, 15 goals)
The German veteran headed to Liverpool already in the twilight years of his career. Indeed, he retired just a couple of years after leaving us, finishing his career with Fulham. He was briefly a regular at Anfield before making way for the up and coming Michael Owen, who burst on to the scene around the same time.
He was brought in by Roy Evans along with Oyvind Leonardsen and Paul Ince, as the Reds looked to add experience to an otherwise youthful squad. His best moment arguably came right at the end of his Liverpool career, when he scored two goals against Hull City on his farewell appearance.
2) Peter Crouch (2005-2008; 134 games, 42 goals)
Crouch came to Liverpool from Southampton, something which is far more common these days, and had a more than respectable three year period at the club – reaching double figures for goals on each occasion. Crouch took 20 games to break his goal duck for the club, but once he did he never looked back.
He notably helped us win the FA Cup in 2006, setting up our second goal for captain Steven Gerrard, and got the winner against Chelsea in the Community Shield a couple of months later. He scored a memorable hat-trick against Arsenal in March 2007 and he ended that season as our top scorer, with 18 in all competitions.
