Álvaro Arbeloa – 2007 (Deportivo de La Coruña)
Arbeloa was brought to Liverpool for £2.6 million to serve as the understudy to Steve Finnan at right-back.
The Spaniard impressed by surviving his baptism by fire of sorts, his first starts coming in the last-16 round legs of the Champions League against Barcelona, with the task of containing a 19-year-old Lionel Messi.
Arbeloa served as a versatile fullback for the Reds from 2007-09, with an ability to play across the backline. He racked up 98 appearances for Liverpool and scored twice before returning to Spain to play for Real Madrid on a five-year contract.
Martin Skrtel – 2008 (Zenit St. Petersburg)
The Slovak center-back joined Liverpool on a four and a half year contract for £6.5 million.
Skrtel’s career was reminiscent of his fellow Red defensemen Daniel Agger – a long-time, reliable piece of the squad – but with fewer injuries to clog up the works. He made 320 appearances for Liverpool across competitions, with 18 goals and 7 assists between 2008 and 2016.
Skrtel was instrumental in the Reds’ 2013-14 Premier League title chase, scoring seven critical goals in the campaign that Liverpool finished in second place just two points behind Manchester City.
Maxi Rodriguez – 2010 (free transfer, Atlético Madrid)
Rodriguez came to Liverpool on a free transfer after an impressive five-year stint at Atlético, within which the Argentinian scored 44 goals and had 20 assists in 157 appearances for the club. His time as a Red offered much less consistency, but Rodriguez was able to register one standout Premier League season in 2010-11, scoring 10 goals in 28 appearances.
Rodriguez left Liverpool in 2012, and only recently retired from playing for Newell’s Old Boys on January 1, 2022, the day before his 41st birthday.
