Antonio Conte blamed a loss of confidence for Chelsea's 3-1 defeat to Tottenham but assured they will continue to fight for a place in the Champions League.
Chelsea are eight points behind Tottenham in the race for the top four after Spurs came from behind to claim a first win at Stamford Bridge since 1990.
Alvaro Morata pounced on an error from Hugo Lloris to give Chelsea the lead, only for a wondrous long-range strike from Christian Eriksen to level matters on the stroke of half-time.
Dele Alli then scored twice in five minutes after the restart to end Tottenham's long hoodoo in west London and pile the pressure on Conte, whose Chelsea future appears in serious doubt.
