Chelsea will be looking to equal a defensive feat that they last achieved in 2008 when they meet Leicester City on Saturday afternoon.
Thomas Tuchel's side make the trip to the King Power Stadium sitting three points clear at the top of the Premier League standings.
Having conceded just four goals in 11 matches, the Blues also head into their next fixture with the best defensive record in the division.
While Chelsea will be focused on collecting all three points, they are also within touching distance of recording four successive away victories in the top flight with the bonus of a clean sheet.
The West Londoners have not achieved that for 13 years, shortly after Luiz Felipe Scolari arrived at Stamford Bridge.
On that occasion, Chelsea went six away games in a row with wins and clean sheets, beating Stoke City, Middlesbrough, Hull City, Blacburn Rovers, West Bromwich Albion and Bolton Wanderers respectively.
