Antonio Conte says his Chelsea team are out of the title race after a humiliating 1-0 defeat by West Ham United on Sunday.
"If you want to stay in the race you need continuity in results. This is not our case. If you lose four games in 16 you're not in the race,” said the Italian coach, who led the Blues to the title last season.
"We have a lot of reason to justify the result against Manchester City - we played after two days.
"When you lose against Palace, when they are bottom of the table, and lose again against West Ham when they are in a bad position - if you lose points in these games, you are not in the title race.
"You have to change. We have to do our best this season, but this season I said it would be very difficult. This is the truth."
