"I am really excited to be signing a new contract with Chelsea," Armando Broja told the Blues' official website.
"Having come through the Academy here it was a special moment for me to make my first-team debut last year, before gaining further experience on loan at Vitesse last season.
"I want to build on these foundations and I am really looking forward to progressing and making an impact at Chelsea in the years to come."
The 19-year-old striker has signed a five-year deal with Chelsea after a successful loan spell with Vitesse where he scored 11 goals in 34 games.
The Albania international has already made his Premier League debut for Chelsea and is expected to stay with the first team at least for the pre-season where he'll hope to impress Thomas Tuchel.
