Armando Broja has signed a long-term contract at Chelsea that commits him to the European champions until June 2026.
Albania striker Broja, who turns 20 in September, has progressed through Chelsea's youth ranks and made his first-team debut as a substitute against Everton in March 2020.
He spent last season on loan at Vitesse Arnhem, scoring 11 goals in 34 appearances for the Eredivisie side.
Olivier Giroud's move to Milan, which was finalised on Saturday, and speculation linking Tammy Abraham with a move away from Stamford Bridge means Broja could play his way into Thomas Tuchel's plans for the 2021-22 campaign.
"I am really excited to be signing a new contract with Chelsea. 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," he told Chelsea's official website.
"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."
Chelsea begin their Premier League campaign at home to Crystal Palace on August 14, three days after taking on Villarreal in the UEFA Super Cup in Belfast.
