Jose Mourinho has warned his Chelsea stars he won't tolerate any repeat of their flop against Newcastle when they host West Bromwich Albion on Saturday.
Mourinho's men go into the Premier League clash on the back of a 3-0 Champions League win against Schalke on Wednesday, but Mourinho is still smarting after their lacklustre 2-0 defeat at Newcastle last weekend.
The Blues boss was left fuming at his side's performance at St James' Park and revealed it caused him to get angry with the squad for the first time since his return to the club.
With second placed Chelsea hoping to cut the five-point gap to leaders Arsenal, Mourinho has made it clear he doesn't want to have to lose his cool again.
Asked if it was the first time the players had seen a different side of his character, Mourinho replied: "Yes. Because the defeat against Everton was a consequence of what football can be, you never know when you are going to lose or win.
"The defeat against Basel was a very strange one but in the game against Newcastle my feeling was not good from the first minute.
"For the new ones, with the ones I work with for the first time, maybe it was the first time they felt me but I don't want to be scary.
