Every successful team needs a good goalkeeper, and there have been six different winners of the Premier League golden glove since its inception in the 2004/05 season.
At both ends of the Premier League table, if you want to be successful, you need to have a decent guy in between the sticks and you want to keep clean sheets.
We've been looking back over the past 10 seasons of Premier League football – from 2007/08 to 2016/17, where 38 goalkeepers have managed to keep 20 or more clean sheets over that period.

In our quiz below, you have ten minutes to name every goalkeeper to have kept 20+ clean sheets. Some are certainly easier than others and we've been kind enough to give you some clues.
We've told you the clubs they played for in the Premier League since 2007/08, where they've kept a league clean sheet – that is to say, if they have been a team and failed to keep a shut out, that doesn't make the clue.
