Thomas Tuchel says Chelsea must keep their feet on the ground after an excellent weekend for the Blues.
Chelsea went three points clear at the top of the Premier League after they won at Newcastle while both their main title rivals slipped up.
Manchester City lost at home to Crystal Palace and Liverpool drew 2-2 at home to Brighton after being two up.
But Chelsea boss Tuchel dismissed suggestions that those results made his team’s victory even sweeter.
“First of all it’s far too early and second of all we want to focus on ourselves,” he said at his post-match press conference.
“What goes around comes around. There’s a long way to go. If you think we are even happier (because of results elsewhere) this is absolutely not true.
“We should have the feet on the ground. I’m very happy with the team effort today and we don’t celebrate other teams’ results.
“You can lose any match in this league. We focus on us, keep going and see where it goes.”
Newcastle managed to frustrate Chelsea before Reece James put the visitors ahead with a cracking strike and then fired home again to double their lead.
James has scored three goals in his past two league games.
“We don’t need to practice shooting with Reecey – he shoots like a horse,” Tuchel said.
