Chelsea manager Thomas Tuchel says he "feels it personally" when they lose games and he has a "certain anger" to put it right.
The Blues lost only their third game of the season on Saturday against West Ham, following defeats by Manchester City and Juventus in September.
They still remain top of their Champions League group, level on points with Juventus after five games.
Chelsea play Zenit St Petersburg, who are third in the group, on Wednesday.
Tuchel's side have already qualified for the knockout stages but they must match or better Juventus' result against Malmo to go through as group winners.
