Antonio Conte revealed he is struggling to sleep after Chelsea's poor form in the Premier League continued at Arsenal.
The Blues' winless run in the Premier League stretched to three matches on Saturday as they were comprehensively beaten 3-0 at Emirates Stadium with Alexis Sanchez, Theo Walcott and Mesut Ozil on target for the Gunners.
Chelsea, who have not won in the league for nearly a month, slipped down to eighth place following the defeat and are now eight points behind current leaders Manchester City.
