Chelsea boss Maurizio Sarri has wrote off their title chances after defeat at home to Leicester City.
Jamie Vardy scored the only goal of the game early in the second half.
Sarri believes it is "impossible" for Chelsea to fight for the Premier League title this season.
The defeat - their third of the season - leaves them trailing Premier League leaders Liverpool by 11 points but, crucially, only sitting above fifth-placed Arsenal on goal difference.
Sarri added, "After the goal the reaction was, for me, a strange reaction, not in the right direction, not as a team but as 11 different players and so it was very strange."
