Chelsea boss Jose Mourinho explained his blast for his players after last week's defeat at Crystal Palace.
Mourinho slammed their lack of mental toughness following the 1-0 reverse.
After victory over Stoke City, he said: "If I go to a wedding I don't go in jeans. If I leave my house for a walk in Hyde Park, I don't go in a smoking (jacket).
"So when you go to play against Crystal Palace at Crystal Palace, you know the way you have to go. These boys, they have to be able to go away from home and to adapt to the situation. This takes time, let's go step by step.
"In football to be champions and to win titles you have to play in the sun, in the rain, in the cold, in the hot, small pitches, big pitches, direct football, possession football. You have to adapt."
