Chelsea coach Jose Mourinho says he does not want to scare his players but he feels he was right to lose his cool after last weekend's loss to Newcastle.
Goals from Yoan Gouffran and Loic Remy saw the Blues' six-game winning streak come to an end, after a performance the Portuguese trainer later labelled "the worst" of his second stint at Stamford Bridge so far.
But Mourinho, who has also seen his side lose away at Everton and at home to Basel in consecutive games during September, insists his furious reactions are intended to make his players stronger.
"The defeat against Everton was a consequence of what football can be. The defeat against Basel was also a very strange one," the Chelsea boss said at a press conference.
"Against Newcastle, my feeling was not good from 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 go top of Group E, and Mourinho was pleased with the response he got from his troops.
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."
