Chelsea boss Jose Mourinho says he's to blame for their flat performance at Champions League opponents Maribor.
Chelsea had beaten Maribor 6-0 two weeks ago and came to life only after Agim Ibraimi's goal, Nemanja Matic's close-range strike salvaging a draw.
"Many times surprises happen when people are not fully focused, when they believe the game can't be a difficult one," Mourinho said.
"I was conscious of it, but I was not successful in passing over that message.
"If I cannot convince the players that the game is difficult and you have to play from minute one, obviously it's my responsibility.
"Only when Maribor scored did the players realise the game was in danger. After that, a fantastic reaction. We deserved to win, clearly."
