5. Emiliano Insua
Ok, so now were onto the five worst. Even Reds fans may not remember much about Emiliano Insua so underwhelming was his impact at Anfield. The young Argentinian did however make over 60 appearances for the club after a move from Boca juniors in January 2007. Unfortunately Insua just never really cut it in the Premier League and his appearances were born more from necessity after injuries to Fabio Aurelio and the general awfulness of Andrea Dossena. Surprisingly enough Insua remained on the books at Liverpool until 2011 before being shipped off to Sporting Lisbon following a loan spell at Galatasaray. At under
£2 million at least Insua was not an expensive failure, but his poor defensive performances during his spell at Anfield mean he was a failure nonetheless.
