Chelsea defeated Newcastle 3-0.
"They've got a good spirit," said the Toon chief.
"It's really difficult at a big club to sustain the spirit when you've got so many big egos. You can see there's a good spirit even on the bench and I think that bodes well for the rest of the season for them.
"The other thing is the manager, Jose. His record sounds alarm bells out for all the others. They're as good a team as we'll play."
