Unai Emery said Arsenal's impressive win in Napoli to seal a Europa League semi-final place proved his side can mix it with the best.
The Gunners became only the second team to beat Napoli in Naples this season, after Serie A leaders Juventus, with a 1-0 triumph courtesy of Alexandre Lacazette's first-half free-kick.
After the game, Emery said: "I'm very proud of the players, very proud of the work, because here, I think we showed we have the habit to play against good teams with good players and in big atmospheres, have a lot of personality with our idea.
"We wanted to have more possession with the ball, keep more of the ball and control the match with the ball. We didn't do all I wanted, but the positioning in the first half we were very good, pressing well.
"Being in their box a lot of the time, gave us the possibility to score - that was our objective today, and after that to win."
Emery also gave an update on the prospects of injured Aaron Ramsey, who went off with a hamstring problem in the first half - and may not feature again for Arsenal before he leaves for Juventus in the summer.
