Willian says Chelsea have no margin for error if the reigning champions are to maintain their Premier League title challenge at West Ham United this weekend.
Antonio Conte’s side fell short in their bid to wrap up the opening stage of their Champions League campaign as group winners following a 1-1 draw with Atletico Madrid.
The failure to beat the Spanish side means they risk drawing Barcelona or Paris Saint-Germain in the knockout stages of the competition.
Chelsea boss Conte, though, will be anxious his players forget about the European campaign that is now on hold until the New Year, and set about the task of closing the eleven-point gap to Premier League leaders Manchester City.
Saturday’s trip to the London Stadium marks the opening game in this weekend’s round of fixtures and a Chelsea victory would lay down a marker before City meet second-placed United in the Manchester derby the following day.
