Newcastle boss Eddie Howe says victory over Chelsea was a "statement".
Newcastle thrashed the visitors 4-1 on the day.
Howe later said, "It was a real statement of character within the squad. We really asked the players to step up, and we really deserved to win. Big positives from today. The leaders within the group set the tone - Jamaal Lascelles, Kieran Trippier, Matt Ritchie. They make sure we don't surrender."
Teenager Lewis Miley produced a superb pass for Alexander Isak's goal.
Howe said: "The biggest compliment I can give him is the pass for the first goal - an incredible decision, and he has the right temperament. A lot of young players would have wanted to shoot there.
"We have high hopes for him. If you are disjointed and go away from your principles, you will be in trouble. We just try to be us."
