Chelsea lost ground in the Premier League title race after they were held to a 0-0 draw by Everton at Stamford Bridge on Sunday.
The first half was an ill-tempered affair with chances at a premium for both sides. The best opportunity fell to Marcos Alonso, but his volley was parried clear by Everton goalkeeper Jordan Pickford.
Chelsea dominated the second half but could not find a way past Pickford. Eden Hazard fired narrowly wide, Alonso hit the post and Alvaro Morata saw an effort ruled out for offside as the hosts had to settle for a point.
