Chelsea's hard-fought win keeps them top of the table
Leaders Chelsea were made to work hard for a 2-1 win at Watford in one of two games held up by lengthy delays to allow treatment for an ill supporter in the crowd.
Chelsea needed Hakim Ziyech to come off the bench and score the winner 18 minutes from time at Vicarage Road to hold off City and Liverpool at the top of the table.
After a half an hour hold up early in the match as a fan was attended to by emergency services, Mason Mount gave the European champions the lead.
Emmanuel Dennis hit back for Watford on the stroke of half-time and for a while it looked like Chelsea could drop points for the third time in four league games.
But Ziyech's powerful finish from Mount's cross maintained their slender one-point advantage over City.
