Hudson-Odoi has spoken about his love for the club as a new contract looms nearer.
Speaking of the moment, Hudson-Odoi told the official Chelsea website: "I remember him scoring a hat-trick and the third goal was near where I was sitting in the corner.
"He came over to celebrate. Obviously I was happy for the team because they'd won and for him as well.
"When he started celebrating, I was delighted and he just saw me, came over and held my hand. For a young boy seeing a professional footballer coming to do that for you, it was crazy. I was smiling so much."
Now, over five years later, Hudson-Odoi is a star name on the pitch and living the dream.
He said: "You dream of being a professional as a kid, especially at the club I've now been at for so long. You think, 'Can I become like him or at least get to the top where he is?' and I'm now fulfilling that dream.
"It's the boyhood club I've always loved and played for, so I've always felt that that dream is there. Now I just want to carry on and keep going."
