Arsenal forward Reiss Nelson has signed a new four-year deal, with the option for another year.
The 23-year-old academy graduate's previous deal had expired before he committed his future to the club he joined as an eight-year-old.
Nelson made 11 substitute appearances in the Premier League last season, scoring a late comeback winner in the 3-2 win over Bournemouth on 4 March.
Gunners boss Mikel Arteta said Nelson has "tremendous ability".
"Reiss is a player I have admired since the first day I was here," said Arteta. "He has tremendous ability and is such an exciting offensive talent.
