Arsenal manager Arsene Wenger has praised Serge Gnabry for his performance against Tottenham Hotspur in the third round of the FA Cup on Saturday.
The 18-year-old attacker played the entire 90 minutes of the Gunners' 2-0 win at the Emirates Stadium.
"He has had some good games, but maybe we were not at home," he told reporters. "He played well at Swansea [City], at Crystal palace, and overall today he has shown that he is quality. He had a very good game.
"He is a very young boy, he [was born in] 1995 so that shows you that he is very young and he has the quality. He is bright, he has a good football brain. I am a strong believer in Serge because I integrated him at the start of last season but let's not make superstars with one game.
"The top level is [about] consistency but I believe the ingredients are there. He has to show he can turn up with these performances in every game."
Santi Cazorla and Tomas Rosicky scored the goals for the Gunners against their North London rivals.
