Arsenal forward Serge Gnabry has agreed a new 'long-term contract' with the current Premier League leaders.
The 18-year-old made his first Premier League start against Stoke in September and scored his first top-flight goal against Swansea in the same month.
"We signed Serge Gnabry because I believe that he will be a great player," Gunners boss Arsene Wenger told the club's website.
"He's nearly there now, and competes for a regular place in the team."
Gnabry came on as an early substitute for Mathieu Flamini against Crystal Palace last Saturday and a foul on him earned Arsenal a penalty and the opening goal in a 2-0 win.
