English Premier League champions Chelsea endured a third successive goalless draw as they were held at home by 10-man Leicester City.
Antonio Conte's side had drawn 0-0 in two cup games before Saturday's return to the league and were still unable to force a breakthrough after Leicester went down to 10 men when defender Ben Chilwell was booked twice in the second half.
But Leicester held on for the draw which leaves Chelsea on 47 points, the same as second-placed Manchester United, who play on Monday at home to struggling Stoke City.
