A safe pair of hands can make a big difference to a team's title chances, cup runs, league positioning and indeed whether the club decides to keep them or not.
Just ask former Manchester United goalkeeper Massimo Taibi.
Liverpool have had some excellent goalkeepers over the years and have let some excellent ones go who they just couldn't accommodate.
Tottenham's Brad Friedel has become one of the Premier League's most consistent goalkeepers, but he couldn't get a look in when at Liverpool FC. Even Coventry legend Steve Ogrizovic couldn't earn a spot due to the fantastic ability of Ray Clemence.
Here, we'll take a trip down memory lane and recognise 10 of the best goalkeepers that have ever pulled on a shirt for Liverpool FC.
It's important to remember that these players are all noted for their performances for Liverpool, not the performances and/or trophies they may have won playing elsewhere in their careers.
I hope you enjoy.
