Broja was reportedly on the radar of West Ham United, Newcastle United and Everton during the close season but has committed his future to Chelsea after breaking into the first team in the opening weeks of the new campaign.

"I'm lost for words really just thinking about it. It's the club I've dreamed of playing for my whole life, the club that I support and the club that I love," Broja told Chelsea's website.

"I've been here since I was a boy so it's a surreal feeling for me and my family."

The Albania international spent last season on loan at Southampton, scoring nine goals in 38 games in all competitions. He has made three substitute appearances for Chelsea this term.

Chelsea also announced the transfer of forward Michy Batshuayi (28) to Turkish side Fenerbahce on a two-year contract with the option of an extra 12 months.

The Belgian, who was at Besiktas last season in the latest of a series of loans, netted 25 goals in 77 appearances for Chelsea after joining from Olympique de Marseille in 2016.

Thomas Tuchel's Chelsea, languishing in 10th place with seven points from five games, host West Ham United on Saturday.
