He told the Chelsea website: "This is a goal of belief. I used to have a team-mate who told me every ball can be the most important ball of the game.
"This is a clear example, a long ball and a misunderstanding and you have the ball to pass into the net. I was lucky.
"I am feeling good and with high confidence, and feeling better in the system we are playing with more space.
"Hopefully we can keep improving as a team as it is just the beginning of the season and important games are coming.
"We are happy because it is our first win against one of the contenders for the Premier League title."
