Rafa Benitez had a thing for signing full-backs during his time as Liverpool manager.
The Spaniard's first recruit after arriving in June 2004 from Valencia was a swoop for compatriot Josemi, who he later swapped for the little-known Jan Kromkamp 18 months later.
He'd spend big on the likes of Andrea Dossena, £8m from Udinese, and Glen Johnson, £17m from Portsmouth, and also seek out bargain deals for Fabio Aurelio, who arrived from Valencia on a free, and Alvaro Arbeloa, a £2.5m recruit from Deportivo La Coruna.
