Roberto Di Matteo declared himself happy with Chelsea's performance from start to finish after they beat Arsenal 2-1 in Saturday's London derby.
Fernando Torres and Juan Mata scored for the Blues as they maintained their unbeaten Premier League record this season to stay top of the early table.
Di Matteo thought the win was deserved but insists Chelsea are not getting carried away by their strong start.
He told Sky Sports: "I thought we played very well today and deserved to win the game.
"I think it's very difficult when you come to the Emirates and they're a good side but I thought we were excellent today."
Asked to highlight where Chelsea did well, the manager added: "Everything from the start to the end. We never defended too much or too deep, we tried to take the initiative and go forward and try and create chances for us and the game went for us today as well.
"Our pressing was very good. We showed it last week against Stoke as well.
"We'll have to keep working on what we want to do. It's going to take some time so hopefully we can still improve.
"It's one game and it's three points, that's all it is."
The manager was impressed by the way youngster Oscar held his own in midfield, particularly under pressure from Mikel Arteta and Santi Cazorla.
He added: "You can't allow them to get into the rhythm and we did that well. With Oscar on Arteta, and Cazorla, we didn't give them much time and space."
Torres was back to his goalscoring ways but Di Matteo insists he has not had a problem with the striker's performances this season even when he has not found the back of the net.
Asked if the Spaniard is happier and back to his best, the manager said: "I've always said that he was happy.
"You tend to maybe overanalyse a bit too much. I was always happy with his contribution. Today he scored a great goal as well and he was very good."
John Terry was in Di Matteo's starting XI after a turbulent week off the pitch that saw him found guilty of using racist language towards Anton Ferdinand by a Football Association hearing.
The manager added: "He showed his leadership today again and it was right to pick him."
