Billy Gilmour was delighted to make his first-team debut for Chelsea.
The 18-year-old came on as a substitute in the 2-2 draw with Sheffield United two weeks ago.
Speaking after signing a new four-year contract, Gilmour said: "It was amazing to make my debut and for the gaffer to show his trust in me in a tight game.
"I thank him for his faith in me, now I need to make sure it wasn't just a one-off and keep showing him I've got a lot more to give.
"I want to make sure I'm involved with the senior team as much as I can be and try to push for more appearances."
