Goal from Yoan Gouffran and Loic Remy saw the Blues' six-game winning streak come to an end, in a performance the manager later labelled "the worst".

"The defeat against Everton was a consequence of what football can be. The defeat against Basel was also a very strange one," said the Chelsea boss at a press conference.
"Against Newcastle my feeling was not good since the first minute. So for the players I work with for the first time maybe it was the first time they saw me angry.
"I don’t want to be scary I just want to influence their mentality, make them stronger and more professional. So my objective is not to scare, it’s to make them strong."
Chelsea responded to defeat at St James’s Park with a victory over Schalke in the Champions League on Wednesday to put them top of Group E, and Mourinho was pleased with their reaction.
He continued: "The team’s reaction against Schalke was what I want. We didn’t have the best start but the reaction of the team was very good.
"Every time we lost the ball we had 11 players fighting to regain it. The good thing is there was a reaction. They coped well with the defeat."
