Chelsea and Manchester United each extended unbeaten runs but suffered blows to their ambitions with a goalless draw at Stamford Bridge.
Man Utd were trying to close the gap to leaders Manchester City but the closest they came to a goal was when Fred’s long-range shot curled inches wide on 68 minutes.
Chelsea enjoyed the majority of the ball but Olivier Giroud snatched at a first-half shot before Hakim Ziyech was superbly denied by David De Gea.
The visitors threatened a late winner but Scott McTominay was unable to set up a team-mate during a stoppage-time breakaway.
Chelsea are unbeaten in seven matches under Thomas Tuchel and have kept clean sheets in all four of the German's home matches, but they miss the chance to go above West Ham United and into the top four.
Second-placed Man Utd stretch their club-record unbeaten away run to 20 Premier League matches but slip 12 points off top spot.
