Arsenal manager Arsene Wenger has described Serge Gnabry as a "very interesting, promising talent" on the club's pre-season tour of Asia.
The 18-year-old midfielder impressed for the Gunners during Friday's 2-1 win over Urawa Red Diamonds.
"He is 17 years old and he has a presence, power, good technique and can play on both sides," Wenger told the club's official website. "He is a very interesting, promising talent."
Arsenal continue their pre-season preparations against Napoli next Saturday in the Emirates Cup.
