6) Bruce Rioch
Most well known for a short spell in charge of Arsenal, Bruce Rioch is a surprise name on this list, with 16 clean sheets from just 38 games giving him a respectable 42.1%.
5) Carlo Ancelotti
Another ex-Chelsea boss, Carlo Ancelotti was perhaps harshly sacked by the Blues, bringing 33 clean sheets from 76 games, or 43.4% – that, and a double in his first season in charge.
