The 19-year-old has signed a new deal with the Stamford Bridge outfit that will take him to 2026.
He sat down for an interview with the club's official website, discussing his journey with Chelsea so far and how he is interacting with other players within the first team.
He said: "Before we had Olivier Giroud, who's obviously left now.
"He's a top, top striker but there's a difference because Tammy went through the Academy so he understands what I'm going through as well, because he's already done everything that I'm doing.
"He gives me advice all the time and tells me what's good, what's bad, how I can learn, how I can do better.
"Tammy's a really good guy, a nice role model.
"He tries to help me out as much as possible and I try to learn from him and the other players, because there are Champions League winners in the squad, everyone here is a top player. It's just nice to be around people you can learn from."
