Antonio Conte: Chelsea spirit set to earn success
Antonio Conte insists Chelsea will become a much more menacing force after his first competitive game in charge ended in victory.
Diego Costa netted a late winner as the Blues edged out West Ham 2-1 at Stamford Bridge.
"The team played a very good game, with a great intensity and a good spirit," said the Chelsea boss.
"We know that we can improve and we must improve a lot with the work.
"I'm pleased for the attitude and behaviour of my players and the victory is, for me, deserved.
"Now we have to prepare for the next game."
West Ham boss Slaven Bilic felt Costa was lucky to still be on the pitch to drill home from 20 yards in the 89th minute.
The striker escaped punishment for a late tackle on Hammers goalkeeper Adrian having already been booked for dissent.
He said: "He had already been booked and it wasn't reckless and I don't think that it was deliberate but it was quite late, the ball was already gone and he could have, or should have, been booked again, which would mean a red card."
Defender James Collins looked to have earned Bilic's side a point by cancelling out Eden Hazard's penalty.
